Yes, the High Trail runs parallel to the Merced River trail, but up on the slope above to the east. The "mapbuilder" layer in Caltopo is based on OpenStreetMap data. Openstreetmap is a crowd-sourced map. Only trails that contributors have entered will show. In general, it seems to show trails more accurately than the old USGS topos, but as you found out, not all trails have been entered on OpenStreetMap. The High Trail does show correctly on the USGS topo layer in Caltopo and is a well-maintained trail.

You can get a flavor of the Lyell Fork Merced River by exploring just a half mile upstream cross-country from the High Trail. In fact, there are fabulous campsites just that far up. See my trip report from 2016: viewtopic.php?t=15812

Thank you, Phil, for the explanation. I'm enjoying your trip report immensely. It's helpful to know it's maintained so I can plan my daily mileage accordingly.
