Perfect condition until the switchback around 1.4km. There the road would still be easily drivable in a moderate clearance 4x4 (likely AWD) but becomes steeper with loose rocks over the surface and a few water bars for a couple hundred meters. It becomes a nice dirt FSR again when it flattens out. We walked up to access Four Brothers Mtn, as the camp gate and another gate beside the lake on Jones LKW were closed.
