Why Lagoon Valley / Pena Adobe dries this way

Lagoon Valley / Pena Adobe sits in the Bay Area, CA area, on clay soil that holds water over terrain that drains at an even, moderate pace. 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. The NNE-facing aspect keeps the dirt shaded for much of the day, so moisture lingers after rain and snow is slow to clear, and the rolling terrain, about a 6° average grade at 453 ft, drains steadily rather than pooling.
