Wow, what an adventure! And great pictures! That is so awesome you guys are getting those grants from the AAC and CalTopo.
I've primarily been a Gaia GPS user since I have a ton of data in there, but came across CalTopo (I had used it a long time ago, but its way better now) a couple months ago and was super impressed with it and have been using it more.
Thank you so much for sharing your story here, and congratulations on a great trip to an amazing place.
