This is the benchmark on the "top" of Mt Evans. I say "top" because there is another boulder within 20 feet which is about 3-4 feet higher, and another one within 50 feet which is 2-3 feet higher still. However, this is the one with a readable altitude (if just barely). The two devices are my phone in GPS mode, and the controller for Project Yukari, running a program called "Southwest" because I intend to take it on various flights I make around the country in the future. One of the interesting things about this recorder is that it carries a pressure and temperature sensor.
