Crux is a word for climbers describing the hardest part of the climb, and finding the climbs shouldn't be the hardest part of your day. Often, rock climbers go to crags (rock climbing areas), and have trouble finding climbs in their grade or discipline. Crux allows climbers to zoom into a specific area and find climbs, filtering them by either grade or discipline and location. Using the mountain project API, I was able to pin point the longitude and latitude of climbs in all climbing locations.
