significant streams missing in Gaia Topo in Yosemite
In the White Wolf area of Yosemite, Morrison creek is important. It crosses the trail down to the bottom of the Grand Canyon of the Tuolumne. In the spring it can be a hazardous crossing, and it is almost the only water source along a long section of that steep trail. It is entirely missing from Gaia Topo, though clear on USGS and National Geographic maps.
Similarly, the Middle Fork of the Tolumne River goes by White Wolf, and on up alongside the trail eventually leading to Ten Lakes. On Gaia Topo the Middle Tuolumne ends just inside the park boundary at 37.87519, -119.82410
Does Gaia Topo have a different criterion of stream volume or late-summer flow that (and data to support it) that accounts for the disappearance of these streams?

Thanks for the heads up on the missing creeks.
Gaia Topo, as well as several other sources, are based on the crowd-sourced OpenStreetMap mapping project. We wrote a blog post detailing how you can contribute to OSM: http://blog.gaiagps.com/map-your-world-with-openstreetmap/
If you decide to contribute any updates to the OpenStreetMap project, you'll see the changes in Gaia GPS within about a week.0
