37 – Earthquake Interpretive Site

From F190Pilot’s “Pick Your Own Site” 2024 Check In:

“This is the earthquake fault site north of Chilly ID. The turn-off to it is about 6 miles north of Chilly where Trail Creek Rd (from Ketchum) intersects Hwy 93 between Mackey and Challis. From the turn-off the site is about 2 miles from the highway. In October 1983 a 7.3 Richter scale earthquake hit this area. This giant gash in the earth is the result. Borah Peak is in the background of one of these photos….Borah is the highest point in Idaho. Gaia says this site is at 44.16381, -113.86801. Giving it a 2 because of the graded gravel from the highway.”
