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.”

Interesting site.
I remember this 1983 earthquake. Mom threw us under the kitchen table as I watched the power lines dance out the window.
FE701LR did this check-in late on Monday night. Nothing too bad about getting into this site.
Was was looking at the fault and remembering what the 1983 quake felt like in Caldwell and hoping another quake did’t tear open the earth under my feet.
The visible fault line running along the mountain is pretty neat to see.
Very cool
Pretty ride on the hwy. Interesting information about the fault line.
Got Borah in background as reminder of previous attempt to climb being stormed out. Little did I know the weather ahead for the day.
I got this site on Alec’s 3 day 1300 mile ride day 3. you can really see things are moving here.
Fast gravel road in from the highway. Interesting site.
Visited Mt Borah and Earthquake Interpretive sites. Both access roads from the highway are graded gravel. Easy access.
Site 2 of 5 for today Friday April 11th. Great ride
