Description
What starts as their summer vacation in the mountains becomes a mystery for Grayson, Cayden and Ethan as they discover and then chase the cool air coming out of the ground around some rocks. The mystery turns into an adventure as the brothers discover an old skeleton guarding what may be a treasure map. Answers must be found! Exploration must be done! For this quest, the brothers bring out their flashlights, some flares, two large inflatable rafts, their camping equipment, bright spray paint and their large drone. They even enlist the aid of their parents to help in their Adventures Beneath the Mountain.
