Why Folsom Lake dries this way

Terrain & soil

Folsom Lake sits in the Tahoe & Truckee, CA area, on sandy soil that drains fast over terrain that holds water and dries slowly. 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 568 ft, Folsom Lake rides SSW-facing ground that soaks up sun through the middle of the day, which speeds drying and opens the season earlier; the nearly flat grade, around 0.2° on average, lets water sit, so the flat stretches are the last to firm up.
