Back 40 is a mountain bike network in the Bentonville & NWA, AR area. It rides on mixed drainage soil across flat, partial shade terrain — the combination that decides how the dirt holds up after rain and how quickly it bounces back.
Environmental profile
Back 40’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.
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.
Flat trails have nowhere for water to go. Low spots and natural depressions collect standing water and mud that lingers well after the rain stops, so these networks often stay wet longer than the weather alone suggests.
Slopes here are predominantly southeast-facing — a factor in how fast the surface sheds water and dries.
