Why South Mountain Park & Preserve dries this way

Terrain & soil

South Mountain Park & Preserve sits in the Phoenix & Scottsdale, AZ area, on gravelly sandy soil that drains fast over terrain that sheds water and dries quickly. With little tree cover, sun and wind get to the dirt fast. Whether it’s worth riding comes down to how that ground sheds and holds water after rain. That’s exactly what Loam tracks, hour by hour. At 1,381 ft, South Mountain Park & Preserve rides NW-facing ground that keeps the dirt shaded for much of the day, so moisture lingers after rain and snow is slow to clear; the rolling grade, around 11.8° on average, drains steadily rather than pooling.
