Various scientists from different disciplines are involved in the mystery.Many others of course do not believe it exists.
Wikipedia tells us:
"Bigfoot, also known as Sasquatch, is an alleged ape-like creature purportedly inhabiting forests, mainly in the Pacific Northwest region of North America. Bigfoot is usually described as a large, hairy, bipedal humanoid. Many believers in its existence contend that the same or similar creatures are found around the world under different regional names, most prominently the Yeti of the Himalayas.
The scientific community considers Bigfoot to be a combination of folklore, misidentification, and hoaxes, although a minority of anthropologists and primatologists have seriously considered the possibility. Despite its dubious status, Bigfoot is one of the more famous examples of cryptozoology and has become a popular symbol.http://en.wikipedia.org/wiki/Bigfoot
Bigfoot is described in reports as a large ape-like creature, ranging between 6-10 feet (1.8-3.0 m) tall, weighing in excess of 500 pounds (230 kg), and covered in dark brown or dark reddish hair. Alleged witnesses have described large eyes, a pronounced brow ridge, and a large, low-set forehead; the top of the head has been described as rounded and crested, similar to the sagittal crest of the male gorilla. Bigfoot is commonly reported to have a strong, unpleasant smell by those who have claimed to have encountered it. The enormous footprints for which it is named have been as large as 24 inches (61 cm) long and 8 inches (20 cm) wide. While most casts have five toes-like all known apes-some casts of alleged Bigfoot tracks have had numbers ranging from two to six. Some have also contained claw marks, making it likely that a portion came from known animals such as bears, which have four toes and claws. Proponents have also claimed that Bigfoot is omnivorous and mainly nocturnal.
About half of all Bigfoot sightings are concentrated in the Pacific Northwest, with a roughly equal number of sightings spread throughout the rest of North America. Some Bigfoot advocates, such as cryptozoologist John Willison Green, have postulated that Bigfoot is a worldwide phenomenon.[10]"
among many there is a website which attempts to provide the interested reader or research student with a general overview of the biology of the sasquatch to the same degree that one would expect from, say, a bear website.

As an example of the regional types is a picture taken in 1997 by a fire fighter captain on the edge of the Florida Everglades. This Bigfoot relative is known as the Skunkape in the Florida area. The Skunkape has been sighted numerous times and there have also been footprints found and cast. It gets it's nickname from the powerful stench that often accompanies it. Reported sightings of this creature go back 30 years.(The picture is included in the video which will be posted later.)
