Really glad that I was able to drive French Pass for a few years until it was closed by the USFS in 1976, maybe 1977. It was the first trail I ever saw gated off and a precursor of things to come. The 2007 Gazetteer doesn't even show it as a trail anymore. Screw up the trail by not staying on it and it will be closed.
Eccles Pass is still shown in the same Gazetteer, although not named, but it was legal before Eagles Nest Wilderness Area came into being in 1978. Visual images of it, and the friends and the trucks they were driving when we were on it, are still strong in my memory. In a sense, it's good to be old as these trails were, and are, wildly beautiful and stock size tires were enough to do them - in a Cruiser. Not an FJ, but a Cruiser.
EDIT: I just googled eccles pass and the second thing listed on the first website you are directed to was, wait for it, T-SHIRTS!!! (big sigh) I'm going to post a picture of what Breckenridge looked like when I first got there in 1973 and you won't recognize it.
