The Thumb

The Thumb is a region and a peninsula of the U.S. state of Michigan, so named because the Lower Peninsula is shaped like a mitten. The Thumb area is generally considered to be in the Central Michigan region, located east of Tri-Cities, and north of Metro Detroit. The region is also branded as the Blue Water Area of Michigan.

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 almost always extended to include Lapeer and St. Clair counties as well.

Economy

The Thumb region is very flat with fertile soil, the reason for its historical role as a chiefly agricultural area. Major agricultural products include sugar beets, navy beans,corn, fruits, and fish from the Saginaw Bay and Lake Huron. Manufacturing - particularly concerning the Automotive Industry - is also prevalent in Michigan's Thumb. Many different types of industries can be found in the thumb, mostly located in the southern portion of the region near the larger metropolitan areas of Detroit and Flint.

The Thumb (mountain)

The Thumb is a mountain in the Five Fingers Group, a group of summits on the divide between Pitt Lake and Coquitlam Lake and north of Widgeon Lake, in British Columbia, Canada.

The Thumb (Omineca)

The Thumb is a mountain located 7 km (4 mi) south of Sitchiada Mountain on the east side of Bear Lake, on the divide between the upper Omineca River and the basin of the Bear River in the Omineca Country of the Central-North Interior of British Columbia, Canada. As the Omineca is part of the Arctic Ocean drainage, via the Peace and Mackenzie Rivers, and the Bear is in the basin of the Skeena River, which drains to the Pacific, The Thumb is located on the Continental Divide.

Geology

The Thumb is the most abundant feature in a cluster of approximately seven volcanic plugs combined with dikes, lava flows, and leftovers of eroded cinder cones. Even though the plugs have not been dated, the current form of loose scoria and related intravalley lava flows to the current topography indicates they formed in the past two million years of the Quaternary period.

The vertical structure of The Thumb develops a prominent monument rising approximately 189 m (620 ft) above smoothly rising landscape along the ridge of the Connelly Range. The Thumb is largely made of columnar basalt bounded by pockets of breccia comprising clasts of the basal sandstone that formed during the Paleocene period.

Thumb

The thumb is the first digit of the hand. When a person is standing in the medical anatomical position (where the palm is facing to the front), the thumb is the outermost digit. The Medical Latin English noun for thumb is pollex (compare hallux for big toe), and the corresponding adjective for thumb is pollical.

Definition

Finger and thumb

The English word "finger" has two senses, even in the context of appendages of a single typical human hand:

Linguistically, it appears that the original sense was the broader of these two: penkwe-ros (also rendered as penqrós) was, in the inferred Proto-Indo-European language, a suffixed form of penkwe (or penqe), which has given rise to many Indo-European-family words (tens of them defined in English dictionaries) that involve or flow from concepts of fiveness.

The thumb shares the following with each of the other four fingers:

Backhoe

A backhoe, also called a rear actor or back actor, is a piece of excavating equipment or digger consisting of a digging bucket on the end of a two-part articulated arm. They are typically mounted on the back of a tractor or front loader, the later forming a 'backhoe loader' (colloquially known as a JCB in Ireland and UK). The section of the arm closest to the vehicle is known as the boom, and the section which carries the bucket is known as the dipper or dipper-stick (the terms "boom" and "dipper" having been used previously on steam shovels). The boom is generally attached to the vehicle through a pivot known as the king-post, which allows the arm to slew left and right, usually through a total of around 180-200 degrees.

Characteristics

The name "backhoe" refers to the action of the shovel, not its location on the vehicle : a backhoe digs by drawing earth backwards, rather than lifting it with a forward motion like a man shovelling, a steam shovel or a bulldozer. Confusingly, the buckets on some backhoes may be reconfigured facing forward, making them "hoes". However they are not as effective in that orientation, since the dimensions of the various components are optimized for backhoeing. Most backhoes are at their strongest curling the bucket, with the dipper arm next most powerful, and boom movements the least powerful.
