Thank VS....
It was taken about five miles from my house in Southeast Idaho at the bottom of one of the trails I ride.
The Road is lower Sulpher Canyon where they used to mine Sulpher back in the 1800's.....and yes it does stink a bit down there....
Here's a pic of what you find in the old mines sometimes....
The white stuff on the ground is Raw Sulpher.
And this one was taken at the top of a cross over trail between Wood and Upper Sulpher Canyons looking toward Mt. Sherman.
Picture was taken with my old P&S Kodak....
