El Mirage Lake, Dry lakebed in San Bernardino County, US.
El Mirage Lake is a dry lakebed in San Bernardino County that stretches across several miles with a flat, hard clay surface. This solid ground formed from ancient silt deposits that hardened over time into a smooth racing surface.
The Southern California Timing Association has conducted speed trials on this lakebed for over five decades. These racing trials have produced numerous records and established the location as a testing ground for vehicles.
The flat expanse serves as a gathering point for recreational enthusiasts who practice land sailing, ultralight aircraft flying, and remote-controlled airplane operations. Visitors come here to test their skills in these sports against the open landscape.
Be prepared for seasonal closures during wet conditions, as moisture can damage the surface and make it unsafe. Check current conditions before planning your visit, since weather can change the accessibility of the lakebed.
The surface requires careful monitoring because vehicle use can quickly create ruts and damage if conditions are not ideal, posing safety risks. This sensitivity to traffic is why authorities close the lakebed during rainy periods to protect its integrity.
