LOW MESA, SAN BERNARDINO COUNTY. 
This station is not on any prominent point and is difficult to describe. 
The country for miles around it is much alike. The best way to reach 
it is to take the road from Parker to Needles and follow it until the 
6-mile post is passed. About 200 yards beyond the 6-mile post the 
road goes over a high narrow backbone of mesa and down into a low 
wide stretch of wash country. From the road at this high place sig- 
nal is in sight about 2 miles south, 66° west, on a white mesa ridge, 
with a long black hill in the distance for a background. Get the 
direction from this place, then follow the road a little farther, then 
leave it to the right and go straight across low flats and washes until 
the main wash is crossed close under station.
