Environmental profile

Tamarancho’s drying behavior comes down to what Loam measures for this exact location:

Mixed drainageLoam

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.

Partial shade27% canopy

A mix of shaded and open sections. Sun-exposed stretches dry quickly while tree-covered sections hold moisture longer, so conditions can vary noticeably across the network — rideable in one zone, still damp in another.

Rolling10° avg

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 southeast-facing, with about 2% rock fragment content in the soil — a factor in how fast the surface sheds water and dries.
