Sardine lake John Muir Wilderness (little onion valley)

[walkawhile]

Has anybody here explored Little Onion Valley and Sardine lake? Its on my Tom Harrison Map but I've never heard of it. Any beta would be appreciated! I'm planning on heading over Kearsarge and meeting some folks at Roads End. Then we'll do the Rae Lakes loop. Since I have some extra time I thought I'd explore the area around Onion Valley. Cheers!

I haven't been there but did some work adding this trail on OSM (it's on Caltopo now too). From satellite it looks like the trail is pretty good up to the turnoff to the old mines around 10,500ft. The forest service has a decent track above that point, though it largely mirrors the old USGS quads and was probably just a ranger looking for remnants of a trail while following the map. It looks like it's returned to nature, if it was ever really there in the first place.
