Thanks! I hadn't seen either of these sites before.
I really like CalTopo, but I've found two bugs in the trail data just along the Merced River. There's a "low" trail at the bottom of the valley and a "high" trail on the south-facing slope. About a five-mile chunk of the "high" trail around Washburn Lake is missing. And the "low" trail is frustratingly discontinuous at the bridge over the Merced Peak Fork. (They appear to use OpenStreetMap data, which doesn't have the discontinuity.) Any idea how to fix this?
Meanwhile, PlotARoute is missing about a 5-mile chunk of the Illilouette Creek trail. And there's something really funny about the elevation profile that it generates.
