Tilden is a mountain bike network in the Bay Area, CA area. It rides on mixed drainage soil across rolling, exposed terrain — the combination that decides how the dirt holds up after rain and how quickly it bounces back.
Environmental profile
Tilden’s drying behavior comes down to what Loam measures for this exact location:
This network sits on mixed or loamy soil — a blend of particle sizes that balances water retention with reasonable drainage. Drying time falls between sandy and clay soils, typically a day or two after significant rain.
Open terrain gets direct sun and wind from all sides, which speeds evaporation significantly. Exposed trails are usually the fastest to rebound after rain — a bright, breezy afternoon can make a big difference.
Rolling terrain drains reasonably well and tends to be forgiving in variable conditions — enough gradient to shed water without the consequences of steeper ground.
Slopes here are predominantly east-facing — a factor in how fast the surface sheds water and dries.
