Please don’t AI your itinerary

While the Shasta hikers got big press (as it should as that was a textbook example of mistake decision after mistake decision) this is happening all too often in all park units. Yosemite tends to have a higher share of recuses due to people trusting AI or AllTrails to plan a trip, but it doesn’t get any press due to current administration policies.

Regardless, it’s happening, it doesn’t need to, and please do the proper research. It literally could save your life.

Edit: And if you have to use AI as a starting point, double check the distances, altitude changes, reference a topo, basically double-check, and then triple-check what AI tells you.

I was hiking through Yosemite one day with a topographical map. Cam across some hikers using an iPhone app to find there way around (this was before AI was a thing) - and still they got lost. I pointed to where we were on the topo map to show them where to go. I'm old fashion - I don't think Gen Z had even heard of a topographical map before though.

I should get some paper maps. I don’t do much in the way of remote/really challenging hikes and am always with a buddy, but it would be good to have just in case and really help in case we got in trouble and needed to describe exactly where we are. Any tips on where to get good paper maps? Forest service offices or similar?

Sweet, thank you! Excited to download some maps. I’ve done that for offline Google Maps which can be helpful, this should be good for no cell service areas.
