Keyhole Canyon (view east from Hwy 95). |
Overview
Keyhole Canyon is an amazing archaeological area with many
petroglyphs and a few pictographs. Most of the petroglyphs are
geometric symbols rather than representations of physical things, but a
few petroglyphs depict bighorn sheep, lizards, and humans. In most
petroglyphs sites, the rock art is fairly close to the ground, but here
they are unusual because so many are very high on the cliffs.
Keyhole Canyon cuts into a ridge of hard granitic rock that
juts so abruptly out of the desert flats that you can drive right up to
the edge of cliffs at the base of the mountain. The mouth of the
canyon, about 50 yards wide, opens onto the parking area. About 175
yards up the canyon, a 50-ft, water-sculpted and polished pour-over
blocks easy progress up the canyon. The short canyon creates the
feeling of being in a deep alcove in the cliffs rather than being in a
canyon in the mountains. |

Many rock faces,
especially those facing south and west, are covered in desert varnish,
a naturally occurring dark patina that forms on the surface of rocks in
the desert. Native peoples created petroglyphs by pecking away the
desert varnish to reveal the underlying light-colored granite rock.
Native peoples also used pigments to paint images, a few of which can
still be seen. There are also some unusual petroglyphs that are
actually carved into softer parts of the rock; some of these appear to
be extremely old.
Access is via fairly good dirt roads. The first mile or so is
a bit bouncy (like moguls on a ski slope), but there are no rocks and
little loose gravel. The next part, a powerline road, is a fine,
maintained dirt road. The last part provides three choices of gravel
versus rocks. High-clearance vehicles should have no problem with the
road, and carefully driven sedans should make it too, at least to
within 0.35 miles of the parking area. Four-wheel-drive is not
required. Cell phones do not work from the end of the road, so
don't get stuck in the loose gravel at the mouth of the canyon. |
|
There are many rock faces (panels) in the area with
petroglyphs that are easily accessible from the ground; other
petroglyphs are high on the canyon walls. Most of the petroglyphs are
located on the north wall of the canyon and along the west-facing
cliffs north of the mouth. At the mouth of the canyon on the north
side, large boulders provide surfaces for many fine petroglyphs. At the
mouth of the canyon on the south side, there are some nice petroglyphs
on the west-facing wall just above the parking area. There are a few
more petroglyphs farther south along the mountain.
There are so many petroglyphs at and near ground level that
there is little need to climb the walls to get close-up views of the
petroglyphs farther up. If you do climb to the higher ones, don't
climb on the petroglyphs, and keep in mind that the granite here seems
unusually slick compared to the limestone and sandstone that are more
common in southern Nevada. I saw one kid take a pretty good slider into
the wash; fortunately, he landed in soft gravel and walked away. |

Location
Keyhole Canyon is located on BLM land between Boulder City and Searchlight.
Links to Area Map and Site Map.
From Las Vegas, drive south on Highway 93/95 towards Boulder
City. Turn right onto Hwy 95 and drive south towards Searchlight for
15.5 miles to an unnamed road (Keyhole Access Road) to the left (Table
1, Waypoint 15). Keyhole Access Road is 5.8 miles south of Hwy 165 to
Nelson, and 3.2 miles south of Eldorado Valley Road (the last named
road). Watch for a highway sign indicating a road intersection. The
road goes through the barbwire fence at a white cattle guard with a
"designated roadway" sign. There are no other roads in the
vicinity. |
|
Turn left onto Keyhole Access Road and drive east for 2.1
miles to a T-intersection (Wpt. 16) between the second and third sets
of high-tension power lines. The first mile or so of this road is a bit
bouncy (like moguls on a ski slope), but there are few rocks. At the
T-intersection, turn right onto the powerline road (a private road;
note the sign about public use), and drive south on the well-maintained
road for 1.8 miles to the first (Wpt. 3) of three roads that fork off
to the left. This point is less than 0.35 miles from the petroglyphs;
read about the three choices before picking one.
The first road (Wpt. 3) runs southeast for 0.35 miles to the
parking area at the mouth of the canyon (Wpt. 4). This road has some
loose gravel and crosses Keyhole Wash at the mouth of the canyon before
gaining higher and firmer ground of the parking area on the south side
of the wash. This road was fine for my little, 2WD pickup. |
|
The second road (Wpt. 22), 0.15 miles south of the first road,
runs right up the gravel along Keyhole Wash; the loose gravel is fine
for driving downhill, but loose gravel always make me nervious. This
road also gains the higher and firmer
ground of the parking area on the south side of the wash.
The third road (Wpt. 21), 0.25 miles south of the first road
(across Keyhole Wash), is narrow and rocky, but it is the firmest of
the three. There is no loose gravel, but someone might need to walk
ahead of a sedan and kick the larger rocks off the road. This road ends
at the parking area and does not go into the loose gravel. |
Unusual carved petroglyph.

Hours
This area is always open and is a well-used camping area.
There is no established campground, but several large campfire rings
are scattered about, and there is an outhouse at the parking area (bring your own paper).
