Big Hole National Forest was established as the Big Hole Forest Reserve by the U.S. Forest Service in Montana and Idaho on November 5, 1906 with 1,917,100 acres (7,758 km 2). It became a National Forest on March 4, 1907. On July 1, 1908 Big Hole was divided between Beaverhead, Deerlodge and Bitterroot National Forests and the name was ...
The Big Hole has a surface of 17 hectares (42 acres) and is 463 metres (1,519 ft) wide. It was excavated to a depth of 240 metres (790 ft), but then partially infilled with debris reducing its depth to about 215 metres (705 ft). Since then it has accumulated about 40 metres (130 ft) of water, leaving 175 metres (574 ft) of the hole visible.
Big Hole is a large maar (explosion crater) in the Fort Rock basin of Lake County, central Oregon, northeast of Crater Lake, near Oregon Route 31. It is approximately 6000 ft (1820 m) across and 300 feet (91 m) deep. [3] It is close to another smaller, but less-eroded maar crater, Hole-in-the-Ground.

[5] [10]: 10–13 [6] Fossil evidence for an instantaneous extinction of diverse animals was found in a soil layer only 10 centimeters (3.9 in) thick in New Jersey, 2,500 kilometers (1,600 mi) away from the impact site, indicating that death and burial under debris occurred suddenly and quickly over wide distances on nearby land.

The team excavated 200 large bones of large animals which included American cheetah, bison, horses and gray wolf, as well as, innumerable microfossils of birds and reptiles. [ 4 ] The cave remains at temperatures below 10 °C (50 °F) and has 98% humidity which is conducive for the preservation of viable genetic material for analysis.
