Overview
This description of the Tonto West Trail is divided into two parts: (1) an overview of the entire trail, trailheads, and other general information, and (2)
individual canyon-to-canyon segments.
From the camping area on Boucher Creek, it is about 5.2 miles
and 2.75 hours to the wash in Slate Canyon. Water is available in
Boucher Canyon and from a spring below the trail in Slate Canyon;
seasonal water may be available at Slate Wash. This segment of the
trail climbs steeply out of Boucher Canyon, runs down along the edge of
the Inner Gorge beneath Marsh Butte (ridge below Dana Temple), and then
runs back into Slate Canyon. The trail is always faint, and hikers
should expect to spend some time off-route and looking for the trail.
Boucher Creek is in Backcountry Use Zone BN9 (at-large camping), and
after turning out of the Boucher drainage, the trail runs through Zone
BO9 (at-large camping).

The Hike
10. Boucher Creek to Slate Canyon -- 5.2 miles and 2.75 hours
From the camping area along Boucher Creek (Table 10, Waypoint
033), the trail runs down Boucher Creek to the confluence of Topaz
Canyon (Wpt. 034). The trail mostly just runs down the streambed, but
close to camp and near Topaz Canyon, you can avoid walking in the
creekbed by staying along the north wall of the canyon. |

Confluence of Boucher and Topaz canyons (view southeast). |
In this section, the trail runs in the Vishnu Schist, the
ancient Precambrian rock that forms the Inner Gorge. These black rocks
are contorted and contain many ribbons of white quartz (dikes),
revealing a history of tectonic activity, metamorphism, and volcanic
activity. This is the only place where the Tonto West Trail gets this
far down into the Vishnu Schist. The cliffs above the Vishnu Schist are
Tapeats Sandstone, and the Tonto Platform rests on the Tapeats, giving
you an idea of how high up you need to climb to get out of Boucher Canyon.
Before leaving Boucher Creek, consider hiking down to Boucher
Rapids, the easiest side trip to the Colorado River along the Tonto West Trail.
From the confluence of Boucher and Topaz canyons (Wpt. 034),
the trail leaves the creekbed and climbs steep hillsides to the north
to get back above the Tapeats Sandstone cliffs and onto the flats of
the Tonto Platform. The start isn't obvious, so take a minute before
leaving the creekbed to look for the trail on the hillside. After you
get on the trail, it is fairly obvious and easy to follow. From the
creekbed, it is a steep and rocky 0.4 miles to get above the cliffs,
and another 0.3 miles to get onto the flats of the Tonto Platform. |

Faint trail (view east). |
Leaving the creek bed (Wpt. 034), the trail climbs onto a
bench on the north side of the wash, then runs northwest to climb
steeply up the east side of a little rocky ridge to a saddle area on
the ridge just below the Tapeats cliffs (Wpt. 035), which is a good
place to stop and catch your breath. The trail continues steeply up the
rocky hillside to the north, running through a broken section of the
cliffs (left of the white boulders). The trail is steep, rocky, and
loose, but above the cliffs, the grade eases as the trail runs east
towards the river. A short bit of trail runs right along the edge of
the Tapeats cliffs, providing great views into Boucher Canyon (Wpt
036), then the trail angles away from the edge and runs northeast up a
gentle side canyon to get back onto the flats (Wpt. 037).
Back on the flats, it is a brief walk (0.5 mi) to the end of
the bluffs overlooking the river, a point with nice campsites and
another grand view of the canyon (Wpt. 038). This is the point where
the trail turns out of the Boucher Canyon drainage system. Up here, the
trail is easy to follow and well-cairned where needed. |

Faint trail (view north). |
The trail turns and runs north under the face of Marsh Butte
for about 1.6 miles to the edge of Slate Canyon. This section of trail
is fairly easy and well marked. There are rocky gullies to cross, but
the trail is good, the crossings are easy, and the views are grand.
There are marginal campsites on the bluffs just before the turn into
Slate Canyon (Wpt. 039).
Turning into Slate Canyon (Wpt. 040), the trail crosses a
broad saddle with some marginal campsites in a minefield of
prickly-pear cactus. The trail over the saddle is faint, so watch
carefully for signs of the trail and a few cairns. The dense minefield
of low-growing, long needled, prickly pear cactus demands constant
attention if you hike in running shoes. |

Easy trail (view south). |
From the turn into Slate Canyon (Wpt. 040), the 2.4-mile (1.5
hour) hike into the back of Slate Canyon seems long and strenuous, but
this might be because the trail is faint and requires constant
attention. You will spend some time looking for the trail, but the
trail is harder to follow when going west than going east. There is a
trail the entire way, and the general strategy for following it is to
stay low, closer to the edge of Slate Canyon than you might expect. My
voice recording from the trail was: "Follow the cairns with the trail:
if it doesn't look like a trail, you are off route." There are several
off-route cairn trails on the hillside, but they all run too high on the hillside.
From the turn into Slate Canyon (Wpt. 040), the trail curves
to the southwest and gently starts into Slate Canyon. After about 15
minutes, the trail starts into the first of two major side canyons
(Wpt. 041), both of which have two major gullies. In the back of the
first gully in the first side canyon, the trail crosses a wash above a
band of cliffs; there are overhangs below the cliffs that would be good
campsites in the rain; but they get afternoon sun, so there would be no
shade during the heat of the day. |

Slate Canyon (view west). |
In the back of the main part of the side canyon, the trail
crosses a rubble field. There is a good trail with cairns through the
rubble field, but there are extra cairns off-route and uphill from the
trail: follow the cairns with the trail. Starting into the gully, the
trail passes under a catclaw acacia and drops into the bottom of the
gully at the edge of the rubble field (Wpt. 042). The trail goes
upstream for a few steps, then turns right and starts down and across
the hillside until angling up and across the center of rubble field,
heading for very large boulders upstream on the far side. On the far
side of the first side canyon (Wpt. 043), the trail crosses the second
major gully on an obscure trail with few cairns, then climbs steeply
across a hillside and onto a saddle with green and purple dirt (Wpt.
044). This is the high point on the east side of Slate Canyon. |

Trail into Slate Canyon (view west). |
From the high point, the trail runs downhill, quickly crossing
a few more small, easy ravines until it runs over a low saddle a
campsite on the point between the two major side canyons (Wpt 045).
From this saddle, the trail runs oddly; it runs straight down a shallow
ravine to the edge of the cliffs, and then turns west along the edge of
the canyon. Remember, stay low, and stay on the trail.
About 5 minutes beyond that saddle, the trail turns into the
second major side canyon (Wpt 046). The trail runs around the hillside
and into the back of the first major gully (Wpt. 047), which turns out
to be a useful landmark. The trail crosses this gully on the long arc
of a white sandstone pour-over. This pour-over is recognizable by two
huge limestone boulders and a large acacia just above the pour-over, a
chocolate-brown boulder on the edge of the pour-over, and four large
chocolate-brown boulders in the gully just below the pour-over.
A small, shallow gully lies about 150 yards west of this large
gully. On the hillside just past the smaller gully (Wpt. 048), the
faint trail forks, although it looks more like bushes in the trail
rather than a fork. Your experience on the Tonto would tell you to take
the upper fork and stay on the contour, but take the downhill fork.
The lower fork runs easily around the hillside and into the
second major gully in this side canyon. The trail enters this gully in
a rubble field, but there is a trail and cairns to follow. Another
string of cairns crosses the gully higher up; I've been there and done
that; it is not a better way to go. |

Slate Canyon (view east). |
Across the rubble field, but just before climbing the bank on
the other side, the trail crosses a wash (Wpt. 049), passing between a
pair of large sandstone boulders. The upstream boulder is red, and the
downstream one is white (with a large acacia).
At the edge of the wash, you will be facing west, towards the
steep side of the gully and cairns. From the wash, the trail cuts
downstream, and then angles up and right around the cliffs and up a
hillside on an obscure trail. The goal is to scramble, as directly as
possible, up the hillside and to the right (towards Slate Creek). After
a moment or two, an obvious use-trail appears, which is followed up the
hillside to the flats above. |

Slate Canyon (view northwest). |
Atop the bluff (Wpt. 050), the use-trail joins the main trail,
and there is a line of rocks across the main trail as if to say, "don't
go this way," directing east-bound hikers down onto the use-trail.
From atop the bluff (Wpt. 050), a good trail runs north to the
edge of the cliffs overlooking Slate Canyon gorge and a campsite (Wpt.
051). From there, an easy trail runs west towards the back of Slate
Canyon, more or less staying on the contour. Just before getting to the
next little side canyon, a large cairn (Wpt. 052) marks the start of
the route down to the spring in the bottom of Slate Canyon (Wpt. 053).
The route descends a steep, dirt hillside to the wash. I've not hiked
down there, but from across the canyon, it looks like you should stay
left below the Tapeats cliffs and circle around the toe of the ridge to
the spring. |

Ice on creek in Slate Canyon (view west). |
The trail crosses another low saddle with a small campsite
(Wpt. 054) before angling off the side of the cliff and dropping gently
into Slate Creek. The trail runs into the wash on the contour and
crosses the wash on the curve of a pour-over atop the Tapeats Sandstone
(Wpt. 055).
If you are hiking east from here, the trail follows the curve
of the pour-over and cuts back out of Slate Canyon on the contour;
follow the cairns. After about 30 seconds, the trail crosses the mouth
of a side wash, and then cuts up the hillside to run above a little
band of cliffs, still running along the side of Slate Canyon.
There are several campsites at the wash crossing. There is a
small campsite under the juniper on the east edge of the wash. On the
west side of the wash, above the trail crossing, there is a very large
pile of small rocks on the hillside that looks like a giant
agave-roasting pit. There are campsites atop the rock pile and on rocky
ledges just upstream from it. About 1 minute out the trail west of the
wash, a ledge with an overhang make a nice rainy-night campsite for one
or two people. The next campsite to the west is about 30 minutes out
the trail.
There is a perennial spring about 0.5 miles down Slate Canyon
from the crossing, and there may be seasonal water flowing in Slate
Creek or in potholes below the trail crossing. I have read, but cannot
verify, that you can get to the river by hiking down Slate Canyon. |
