Amboy Crater Access Road Under Construction for 15 Days

The Bureau of Land Management (BLM) Amboy National Natural Landmark Recreation Area will be undergoing reconstruction, including paving of the area’s access road beginning June 12, with completion anticipated by June 27, 2010. 

The construction project will provide the public with a smooth all-season paved road, replacing the current largely un-maintained gravel road.  The road will be closed to ensure public safety and to increase project efficiency. 

Visitation to the crater during this period is limited to foot traffic and is not encouraged.  With temperatures well above 100, anyone walking the six miles round-trip to the crater and back should prepare themselves with plenty of water and skin protection.  Hikers will also encounter difficult conditions crossing sand and lava for one mile before reaching the trailhead.  BLM apologizes for any inconvenience this closure may cause, but expect the improvements to greatly enhance the recreation area.

Designated a National Natural Landmark in 1973, Amboy Crater is recognized for its visual and geological significance. Amboy Crater is an excellent example of a very symmetrical volcanic cinder cone. There is a breach on the west side of the crater where basaltic lava poured out over a vast area of 24 square miles, which contains lava lakes, collapsed lava tubes and sinks, spatter cones and massive flows of basalt.  Amboy Crater lies about halfway between Barstow and Needles (about 66 miles from each) off Historic Route 66 National Trails Highway.

For further information, please contact BLM’s Needles Field Office at (760) 326-7000.
