WOLF LAKE, Ill. (KFVS) - Snake Road in southern Illinois may close four to five days early due to recent warm weather.
It normally closes in the spring from March 15 through May 15 to allow snakes and amphibians to migrate from their winter habitat in the limestone bluffs across the road to their summer habitat in LaRue Swamp.
According to the U.S. Forest Service, the gradual, two-month migration event draws in people from across the country.
They said about 66 percent of the amphibians and 59 percent of the reptiles known to live in Illinois are found there.
While the road, Forest Service Road No. 345, is closed to vehicles, it is open to people who want to walk around.
The forest service said special regulations apply to the area.
LaRue-Pine Hills/Otter Pond is a federally designated Research Natural Area and unauthorized collecting or handling of any of these species is against federal and state law.
