I can't say ('cuz I don't know) the answer to your question, BUT...

It is almost EXACTLY 1 mile past (North) of the exit off of 67 @ "Rainbow Falls" (on your right)

to the South Shoot Site (on your left).

I know it's not to the nearest 1/10th of a mile, but from the Rainbow Falls web site: "Rainbow Falls Mountain Trout Inc is located aprox 8 miles north of Woodland Park on Hwy N 67"...then just add in the extra mile.

Does this help?
