Why Captain Ahab/Amasa Back dries this way

Terrain & soil

Captain Ahab/Amasa Back (Moab, UT) rides on gravelly sandy soil that drains fast over terrain that drains at an even, moderate pace. With little tree cover, sun and wind get to the dirt fast. Loam reads that exact ground against live weather, rather than leaning on a regional forecast that can’t tell you what the dirt is doing. The terrain here is rolling (a 5.6° average grade at 4,173 ft) and drains steadily rather than pooling, while the SE-facing aspect soaks up sun through the middle of the day, which speeds drying and opens the season earlier. Named trails in this network include Captain Ahab Trail, HyMasa Trail and Jackson.
