Mount Lamlam (meaning lightning in Chamorro), located in the southwestern village of Agat, is the highest peak on Guam. Though Mount Lamlam is only 1,332 feet high, the distance from the peak to the bottom of the nearby Mariana Trench is perhaps the greatest change in elevation on Earth over such a short distance. The Marianas Trench reaches a maximum known depth of 6.78 miles. If Mount Everest, the highest mountain on Earth at 29,040 feet, was set in the deepest part of the Mariana Trench, there would be 6,760 feet of water left above it. Hikers can reach the mountain trailhead across from Cetti Bay Overlook and summit in about 30 minutes.
