Ft. Irwin, between Los Angeles and Las Vegas, has a unique monument to all the military units that have trained in this desert location. Initially, the squadrons climbed to the top of the rockpile to paint their colors. As time progressed, other units began bringing their own painted boulders with their insignia. These rockpiles are over 15 meters tall. Enter our map and press Spacebar to use our measurement tool to see the size of these boulders for yourself. This map was made with video collected with a Mavic P4 Inspire.
