Can we buy our backcountry hiking maps when we get to Yosemite? If so, where? Normally we would buy them ahead of time, but because of the high snowpack, and uncertainty with our route, I'm wondering if we can wait to buy the maps until we are there and we know exactly where we plan to hike. We are spending 3 nights camping in the valley before we begin our backpacking trip.
Thank you.
