We'd been advised to spend a day hiking to Mirror Lake in Yosemite Valley. Though the suggested route combination was 6 miles including 600 granite steps, we chose a more direct route from Curry Village, that ended up being about the same distance anyway. Ha!
Daddy and I have been using iNaturalist for awhile, and now Asher is using it on a regular basis. I love that he's interested in identifying what he finds. (iNaturalist is a free app that can identify anything living - plants, animals, insects, fungus.... If the app can't identify it based on location and photo, it can be left as unidentified and another user will most likely identify it for you!)
