Far North Death Valley
Eureka Dunes Debris FlowFN7. Location/Access:
(37o 04.568' N; 117o 39.225'W) This debris flow is behind the Eureka Dunes if coming in from the north. From the main camping area at the dunes, continue on the road east for 0.7 miles to a junction. Keep left at this junction and continue an additional 2.8 miles to the lower lobe of this flow. The road requires high clearance and four-wheel-drive because of sand. if you continue 0.6 miles further you will be at the base of the main (upper) lobe of the flow. Continue around to the south side for the best view of the flow's structure.
Best Time: Afternoon.
Geology: This debris flow is best viewed from the top of the dunes, from further up the canyon past the flow itself or from satellite imagery available on the Internet. The flow is big enough to be impressive but not so large as to be difficult to envision its structure. The upper portion of the main lobe is comprised primarily of gray limestone blocks of the Cambrian Bonanza King formation and the base of the main lobe is comprised of brownish blocks from lower formations. The source area is obvious up on the main mountain flank as there are smaller remnants and talus cones in the source area. The best place to view the structure of the flow is around the base on the south side where it has been slightly eroded.
