The Thumb lies in the Flint/Tri-Cities Region.
The Thumb lies in the Flint/Tri-Cities Region.

Much of the Thumb is characterized by rolling farmland such as this

The Thumb is a region and a peninsula of Michigan, so named because the Lower Peninsula is shaped like a mitten; thus the Thumb is the area that looks like the thumb of the mitten. The Thumb is a subregion of the Flint/Tri-Cities region, and the Blue Water Area is a subregion of the Thumb.

The counties which constitute the Thumb are those forming the extended peninsula that stretches northward into Lake Huron and Saginaw Bay. There is no formal declaration for which of these counties are part of the Thumb. However, virtually all common definitions include Huron, Tuscola, and Sanilac counties. This definition is sometimes extended to include Lapeer and St. Clair counties as well. The fact that Lapeer and St. Clair counties are included in the Detroit Metropolitan Area also leads many people to exclude them from the Thumb region.


The Thumb region is very flat with fertile soil, the reason for its historical role as a chiefly agricultural area. Major agricultural products are sugar beets, navy beans,[1] corn, fruits, and fish from the Saginaw Bay and Lake Huron. Manufacturing is dominant in St. Clair County and Lapeer County. Few of the residents commute for work to Metropolitan Detroit or Flint. Large cities in the Thumb area are Port Huron, Lapeer, Marysville, St. Clair, Sandusky, Bad Axe, and Caro. The majority of these cities are in the southern portion of the Thumb.

The Thumb has many notable businesses, many linked to agriculture.

  • Intertape Polymer Group, Inc. has a major factory in Marysville.
  • Cargill Salt operates a large salt mine and factory in St. Clair. This is the only plant in the U.S.A. that produces Alberger salt, which is especially prized in the fast food industry because of its higher volume (due to its unique shape) and lower sodium content (for a given volume, not weight). This is part of Michigan's large salt-mining industry.
  • Cooperative Elevator Company has been named the top Michigan Agriculture Exporter by the Michigan Department of Agriculture.[2] Its headquarters are in Pigeon, and it has branch elevators in Deckerville, Akron, Gagetown, Sebewaing, Elkton, and Bad Axe.

Detroit Edison's St. Clair Power Plant, once the largest in the world.

  • Detroit Edison is the operator of five power plants in the Thumb area: St. Clair and Belle River Power Plants in East China Township, Marysville Power Plant in Marysville , Harbor Beach Powerplant, and Greenwood Energy Center in Greenwood Township.
  • Dow AgroSciences Harbor Beach manufactures agricultural chemicals: weed killer, fungicides, fertilizers and plant nutrients and herbicides.[3]

  • Domtar operates a paper mill in Port Huron.
  • Sensient Technologies Corporation, Harbor Beach, makes food flavors and colors, yeast dehydrated products and vegetable protein extract.[6]
  • Star of the West Milling Co.[7] which has grain elevators in Vassar and Cass City, joined with Eastern Michigan Grain in Emmett.[8]


The Pointe aux Barques Light, near the tip of the Thumb.

Some towns, such as Bay Port, Caseville, Harbor Beach, Lexington, Port Austin, Port Hope, Port Huron, Port Sanilac, Sebewaing, and St. Clair enjoy seasonal tourism, due to their locations on Lake Huron, Saginaw Bay, or St. Clair River. The Thumb lies within the east-central tourism region of the state[9]

The Tip of The Thumb Heritage Water Trail is a nonprofit citizens organization working with the Huron County Parks to establish and maintain a water trail along Michigan’s Lake Huron’s shoreline.[10]

Unique to the Thumb[]

Unique features in the area include the following:

  • Algonac, known as the Venice of Michigan because of its many canals, is a part of the largest freshwater delta in the world, that of the St. Clair River into Lake St. Clair.
  • Bad Axe was named after a broken axe found lodged in the knot of a tree at the clearing of the settlement's chief crossroads.[11]
  • Bay Port, is home to one of the oldest commercial fisheries onthe Great Lakes; Bay Port Fish Company.
  • Harbor Beach is the home of the largest man-made harbor and the Harbor Beach Light.

Traveling around the Thumb[]

A favorite of tourists who visit this area is traveling the Lake Huron and Saginaw Bay shoreline via M-25 (formerly US 25 until 1973). M-25 starts at the end of I-69/I-94 in Port Huron at the foot of the Blue Water Bridge and ends in Bay City. The whole route is about 160 miles (260 km), and passes through quaint cities and villages. Along M-25 you can see five lighthouses: Fort Gratiot Lighthouse, Port Sanilac lighthouse, Pointe aux Barques Lighthouse, Harbor Beach Light, and the Port Austin Lighthouse.

The Great Lakes Circle Tour is a designated scenic road system connecting all of the Great Lakes and the St. Lawrence River.[16] Port Huron in eastern Michigan is a good starting point for the circle tour of Lake Huron. M-25 winds around the Thumb and along the Saginaw Bay to Saginaw and Bay City. Do not forget to go to the beach and walk the boardwalks in Lexington and Port Austin.

Thumb counties[]

File:Thumb Area Michigan Map.jpg

A broad definition of The Thumb area of Michigan; Red shaded areas indicate a narrow definition.


Huron County is located at the tip of the thumb. The county is surrounded on three sides by water – Saginaw Bay and Lake Huron, and has over 90 miles (140 km) of shoreline, from White Rock on Lake Huron to Sebewaing on Saginaw Bay, and more shoreline parks than any other county in the state.
The county's economy relies on agriculture and ranks as one of the top agricultural counties in Michigan. Rich farmland inland produces beans, sugar beets, and grain, including most of the world's supply of navy beans.[25] Tourism is also important to Huron County with bay front and lakefront towns such as Sebewaing, Caseville, Port Austin, Port Hope, and Harbor Beach, attracting tourists from all over. Huron County borders the Saginaw Bay and Lake Huron. There are two state parks – Sleeper State Park and Port Crescent State Park. Three roadside parks – Jenks Park, Brown Park, and White Rock Park. Also, Huron County maintains nine county parks along the shoreline, which are Caseville Park, Lighthouse Park, Stafford Park, McGraw Park, Philp Park, Port Austin Bird Creek Park, Wagener Park, Oak Beach Park, and Sebewaing Park.
The county seat is Bad Axe, located in the center of the county.


The County of Sanilac has the largest area of land in The Thumb. Like other counties, Sanilac has fertile and flat land, great for growing crops. Towns like Lexington and Port Sanilac bring in many tourists from the Detroit Area. Sandusky is the county seat and largest city.


Like Huron County, Tuscola is mostly dependent on agriculture. Industries such as sugar refining and ethanol processing, as well as growing various grains and beans, make up most of the economy. Caro, one of the largest cities in The Thumb (the largest if you exclude St. Clair and Lapeer Counties), is named after Cairo, Egypt and is the county seat. Tuscola County only has 18 miles (29 km) of shoreline along Saginaw Bay, so it is not as dependent on tourism as the other counties in the area. Tuscola County is economically tied to the surrounding region as well as to the Saginaw, Bay City, and Flint areas.


Lapeer County is economically attached to Flint and Detroit. Lapeer derives from the French word for Flint, la pierre. Lapeer's economy depends on manufacturing more than agriculture. Although it is landlocked, Lapeer County has many inland bodies of water such as Lake Pleasant, Lake Metamora, Nepessing Lake, Bronson Lake and Barnes Lake. These lakes bring in many campers and tourists. Lapeer County's geography is very different than any other county in The Thumb. Lapeer County is considered part of the Detroit Metropolitan Area, which leads many people to exclude Lapeer County from The Thumb region.

St. Clair[]

St. Clair County has the largest population in The Thumb. St. Clair County is considered to be a part of Southeast Michigan and the Detroit Metropolitan Area, which leads many people to exclude St. Clair County from The Thumb. Many residents farther north in The Thumb, especially Sanilac County, travel to Port Huron for shopping and work. It is the farthest county to the east in Michigan, and most of the eastern border is the St. Clair River, which separates Michigan from Ontario. For the most part, St. Clair County is flat and agricultural, with a landscape similar to that of other Thumb counties, but manufacturing dominates in and around Port Huron.

Disputed regions[]

Some areas of the thumb are debatable, but nearly all definitions will include Huron, Sanilac, and Tuscola Counties, known as the tri-county region. Disputed areas include:

The Blue Water Area[]

Map depicting the Blue Water Area.

The Blue Water Area is a subregion of the thumb, describing St. Clair County, parts of Sanilac County, Northern Macomb County, and Eastern Lapeer County. It is so named because of the Blue Water Bridge and the area's many bodies of water. Sometimes the definition is extended to include all of the Thumb and even Eastern Michigan. A simple definition of the Blue Water Area is the area surrounding Port Huron where residents regularly travel to Port Huron for shopping and work.

Discover the Blue[]

Discover the Blue is a promotion by the Blue Water Area Convention and Visitor's Bureau[26] to attract visitors to the shoreline of eastern Michigan. Communities participating in Discover the Blue range from Algonac (at the southern end of the Thumb) to Port Austin (at the tip of the Thumb).


Land features[]

See also List of Michigan state parks and geography of Michigan.

  • The Thumb's landscape ranges from a flat sandy plain, that hugs the shores of Lake Huron and Saginaw Bay, to a gently rolling topography, which is fertile and well suited for agriculture. Perhaps, the most unusual geographic formation, however, is a rugged glacial ridge, known collectively, as the Hadley Hills, which extends in a northeasterly direction through the center of The Thumb, from the southwestern portion of the peninsula.
  • All counties except for Lapeer border the Saginaw Bay or Lake Huron.
  • The places with the highest elevation are all associated with the Hadley Hills, and are located in Lapeer County, they are: Pinnacle Point, at 1,262 feet (385 m), Kerr (Cemetery) Hill, at 1,258 feet (383 m), both in Hadley Township, Mt Christie, at 1,251 feet (381 m), in Metamora Township, and a point near Mayville, reaching up to 1,050 feet (320 m) above sea level.
  • The lowest place in the Thumb region is in the Saginaw Valley, the far western part of the thumb, at a low 585 feet (178 m) above sea level.
  • Huron County is very flat and is home to wind turbines and large fields.
  • The "tip of the Thumb" is Pointe Aux Barques, between Port Austin and Grindstone City.
  • Marlette is also called the "heart of the Thumb" because of its central position on the peninsula.

Major rivers[]

The Thumb has many waterways.

  • Cass River has many branches, one of which flows into the Shiawassee River in the Shiawassee National Wildlife Refuge at 43°22′42″N 83°59′04″W / 43.37833, -83.98444 less than 1 mile (2 km) from where the Shiawassee merges with the Tittabawassee River to form the Saginaw River
  • The Pinnebog, Shebahyonk, and Pigeon Rivers all rise in the center of Huron County and empty into the Saginaw Bay.
  • St. Clair River, connects Lake Huron to Lake St. Clair, and is the farthest east border in Michigan. It forms a low impression in eastern St. Clair County, and has a delta at its mouth (North America's largest freshwater delta), which includes Harsens Island and Walpole Island, Ontario. Ferries cross the river at Algonac and Marine City, these being international border crossings.
  • Black River rises near Minden City and flows into the St. Clair River at Port Huron. The Black River forms a basin in Sanilac County, and northern St. Clair County.
  • The north branch of the Flint River lies in northern Lapeer County. It rises near North Branch. The southern branch flows through the central and southern portion of Lapeer County, and merges with the North Branch just north of the Holloway Reservoir.

History and local culture[]

Naming and founding of the Thumb[]

The earliest name for the Thumb of Michigan was Skenchioe, which is shown on early maps in the late 17th century and is of Iroquois origin. Skenchioe was the early home of the Native people called the Fox. There is no definite documentation on the meaning of the name Schenchioe although the name red fox is implied. The Onondaga word for a champain or large plain is uchwuntschios and "ganhuntios" while sgechnaxen means red fox.

Maps from the early 18th century, show the Thumb of Michigan as Le Pays Plat, which is French and means the Flat Country. The British used this name in maps of the late-18th century calling the Thumb of Michigan in English the Flat Country.

The Thumb of Michigan county name Tuscola is probably of Chippewa/Ottawa origin and likely means shelf, dish, or plate like land—Flat Country. The Chippewa and Ottawa often used bark from a tree or a shell as a plate. Their words tessi aki means plateau, tableland, or flat country. Esse in Chippewa/Ottawa means shell, and "essimig" means a breast-plate.


Persons of European ancestry have formed the overwhelming majority of the population since the late 19th century. The land was settled mostly by English and Scots-Irish immigrants, many of whom arrived from Canada. Other settlers of the same ancestry migrated from eastern states such as New York, Pennsylvania and New England. Later 19th and 20th century residents included Polish and German immigrants who migrated from Europe through the Detroit area. Many of the customs, much of the regional lifestyle, and even the local accent, strongly reflect these origins. Examples are polka shows on local radio stations and the Kinde, Michigan Polkafest. These European latecomers, arriving many years after the initial waves of arrivals to the Atlantic coast region from Europe, encountered aboriginal peoples for whom many sites in the Thumb were named. The name of Tuscola County was derived from a native word, Saginaw (both the city and county) is taken from an Ojibwe term, and Sanilac, which is the name of a county, is believed to be a Wyandotte name derivation, as well. Among other Thumb place names, Sebewaing is another location with a name derived from the Ojibwe. These tribally-influenced place names greatly outnumber those of any Thumb sites which may have been named with strictly European-influenced words.

Historical events[]

  • The great Thumb Fire took place on September 5, 1881 in the Thumb area of Michigan. The fire, which burned over a million acres (4,000 km²) in less than a day, was the consequence of drought, hurricane-force winds, heat, the after-effects of the Port Huron Fire of 1871 and the ecological damage wrought by the era's logging techniques.
  • The Great Lakes Storm of 1913 was a November blizzard with hurricane-force winds which devastated the Great Lakes Basin in the United States Midwest and the Canadian province of Ontario. The storm battered and overturned ships on four of the five Great Lakes, particularly Lake Huron.
  • The Port Huron area is one of oldest settlements in the state of Michigan.
  • Colonial forts such as Fort Gratiot (north of Port Huron) and Fort Sinclair (near present day St. Clair) were built along the St. Clair River.
  • Bad Axe was named so because Captain Rudolph Papst found an old axe in 1861, when he was clearing land for the present-day Huron County seat.

Area Amtrak stations are in Lapeer, Port Huron, and Flint. Local railroads are the Grand Trunk Western Railroad, CSX Transportation, Canadian National Railway, and the Huron and Eastern Railway. Pere Marquette Railway was a railroad that had lines throughout the Thumb; its lines are now either abandoned or in use by CSX, or Huron and Eastern.

Major railroad centers are Vassar, Bad Axe and Port Huron.


The only international airport in the Thumb is St. Clair County International Airport about 6 miles (9.7 km) outside Port Huron. City airports include: Caro Municipal, Dupont-Lapeer Airport, Huron County Memorial Airport, Marine City Airport, Marlette Municipal, Sandusky City, and Yale Airport. Scheduled airline service is available from MBS International Airport[34] in Freeland, Michigan and Flint Bishop International Airport.[35] While neither of these airports is in the Thumb, both are relatively close by.

Area codes[]

Area code 989 covers about half of the Thumb: Huron, Tuscola, and far northern Sanilac County (and the Marlette, Michigan area). The Thumb's other half is covered by area code 810, which takes in most of Sanilac, Lapeer, Genesee and Saint Clair Counties. All of Macomb County is served by area code 586, as is a small part of south-western Saint Clair County.
