DIRECTIONS |
Take Arizona
I40 to exit 37. Head east on Griffith Rd (turns to dirt immediately
east of the offramp) about 0.4 mi to a north-south frontage road.
Turn left (north) and continue about 2.7 miles to the control point.
This road is probably passable by 2WD vehicle but your mileage may
vary.
|
COMMENTS |
The dirt road
out to the control point is not heavily trafficked. While it's about
three miles back to the interstate, be sure to bring water, a spare
tire, tools, hat, etc. During the summer the hike can be lethal
if you're not prepared.
The mountains
immediately to the east are the Hualapais, with a maximum elevation
of over 8400'. A BNSF radio site is atop this range at the north
end providing road, pbx and ATCS channels.
There may also
be another radio site nearly due south in the Mohave Mountains at
Crossman Peak. This might also be ATCS (or maybe it's the only one?)
