About 10 miles west of Ehrenberg post-office, on top of a flat sand 
mesa on a point as high as any about a mile from where the sand hills 
join the Colorado River bottom. To reach it from Ehrenberg take 
the road to Blythe's ranch until roads fork, then take left-hand road 
a short distance, then leave the road and go straight toward a flat- top

Keep this direction until the valley is crossed and a flat sand mesa is 
reached. Signal is on this mesa and will show for several miles in 
any direction.
