Field Test: Invited backpacking to a little-visited corner of Rocky Mountain National Park, I contributed a custom MyTopo map to the group. MyTopo’s simple yet brilliant four-step online process centers routes and customizes scale, then prints bespoke maps on waterproof, tear-resistant paper. All proved crucial when we had to find our way through sodden marshes and beetle kill forests as rain turned to snow. Search by place name, GPS coordinates, or USGS Quads.
Why It’s Timeless: Digital navigation tools are great, but it’s best to have a hard copy in the natural world. From $30 (18×24-inch); mytopo.com —Olivia Dwyer
