I know that Roach's book says it's 4 miles round trip from the 4x4 parking lot, but that's not correct - it's a bit more than 7 miles. It is almost funny how influential his book is - everyone on the trail the day I climbed was commenting that the mileage was wrong - I guess we all have our own dog-eared copies. I'll upload a GPS track and Topo USA map that shows the mileage.
