It is not too far south of the Borrego-Salton Seaway about halfway between the two. 17 Palms, 5 Palms and Una Palma are all right near each other and the Pumpkin patch not too far away. Very northern edge of the SVRA area.
The actual trail to it from the north is Arroyo Salado. 3-4 miles from the highway. THen pumpkin patch another 3 miles further.
If coming from ocotillo Wells You go north till you come across the Cut Across Trail, take that east all the way to the end and keep going north as much as possible.
Course having a map will help a LOT finding it
For google maps/earth 33°15'17.34"N 116° 6'38.63"W
17 Palms has a "mail box" with notbooks and stuff for signing in and one had a treasure map! THough like all treasure maps, half of it was missing
