If you’re in the Denver-Boulder area, looking for a hike with incredible views, without going deep into the mountains (just a short drive from the University of Colorado at Boulder), check out Lost Gulch. The Rangeman GPRH1000 — with 6 sensors to calculate altitude, temperature, barometric pressure, and more — was photographed along the Front Range, at the Lost Gulch on Flagstaff Mountain in Boulder, Colorado.
