I've never been to La Bohn Gap but I've considered going there, and I was always confused by how the map didn't seem to match up to the Harvey Manning 100 Hikes description. Now I know why!
The new TF layer on Caltopo is also really interesting. Does anyone know how it's compiled and how it differs from the Mapbuilder layer?

I suppose that would be true if you went the wrong way (far right) before reaching the top of the pass and La Bohn Lakes.

FWIW: When my son and I climbed Mt Hinman in 2003, we camped at Williams Lake, hiked up though Chain Lakes to the pass between Chain Lakes and La Bohn Lake and then headed east up Hinman. Fred Becky in the Cascade Alpine Guide refers to this pass as "La Bohn Gap"
La Bohn Lake lies NE of this gap and La Bohn Peak lies SW.
In older USGS maps of the area the "L" of "La Bohn Gap" is shown on the saddle between Chain Lakes and La Bohn Lake and the center of the text "La Bohn Gap" lies on the saddle between Chain Lakes and Lake Rowena.
The terrain between that saddle and Lake Rowena is very steep and not particularly useful as a travel route and there aren't any mines in the Lake Rowena basin that the miners would have been travelling to and from. There are numerous mines in the Chain Lakes area. There is old mining equipment and mines in the Necklace Valley.
So which is easier to believe: 1) That miners labeled a pass they didn't use very much and off to the side of their usual travel route with the same name as closer by features. 2) A USGS clerk in the 1960s who had never visited the area made a mistake placing a label on a newer higher resoution map.

You may inspect the historical USGS maps of the area yourself
https://ngmdb.usgs.gov/topoview/viewer/#14/47.5605/-121.2373
Here is an inset of the 1902 map where the "L" of "La Bohn Gap" lies on the saddle between Chain Lakes and La Bohn Lakes -- notice too the shapes of Williams lake and Lake Rowena are significantly different from modern maps. Also note that the "I" in "Iron Cap Mtn" is on the summit. That name isn't centered on the summit.

Since 2017 the updated USGS topo maps show La Bohn Gap as the pass between Chain Lakes and La Bohn Lakes -- you can inspect using the link above or just look at this inset
