Flat Top Mesa:

Runway: 12/30

Length:1061x50' usable

Runway 30 uphill (first 734' unusable due to washout and erosion-threshold marked with a pile of white logs on left side) landing short has dire consequences.

Runway 12 downhill ( approach end sits atop a 650' vertical cliff face-extreme caution required).

Extreme caution required-this is a very challenging airstrip due to high altitude and hot temps (DA comes into effect), concave landing surface from old washout, turbulence, and typical late day crosswinds that swirl on the airstrip. Runway 12 approach end usually has intense thermal activity from daytime heating of the cliff face and wind activity. Active wildlife area (bears, cats, etc).

Rustic strip, probably 800' long. Best landing is towards the west, as the strip goes uphill to the west. Narrow strip with cedars on both sides. Small parking area at the western edge of the strip on the edge of the cliff, but it was big enough for our 3 planes. Nice campsite with a fire ring tucked in the trees at the on the north end of the runway, just above the cliff. Old uranium mining paraphernalia and some old mine shafts within 200 yards of the strip which were cool to explore. Beautiful view down into Gateway Canyon.

Threshold from the east marked with logs on both sides: touching down prior is very rough. Off-camber landing area, rolling, and some small foliage. A fun and challenging strip. I would venture to say for most one-way T/O to the east(downhill)

Flat Top Mesa was a mining strip used for Uranium dating back to the 50's. Exploring around the plateau will uncover many mining ruins and artifacts. Be careful and mindful that this was Uranium mining and to reconsider digging through or picking up any mining ruins.
