DRIVING ROUTE 1
- Take the 210 freeway east to Baseline Road exit in the City of Claremont.
Turn left (west) at the bottom of the off-ramp onto Baseline Road.
- Almost immediately, take the first right (north) onto Padua Ave.
- Go 1.8 miles north on Padua to the intersection with Mount Baldy Rd.
Turn right (northeast).
- Take this road northeast and then north about seven miles to Glendora Ridge Road in Mt. Baldy Village. Turn left.
- Go about 1 mile to Cow Canyon Saddle with a parking lot on the right. Park here. Ample parking.
Note: There is a good parking lot for ridesharing in this area.
To get there, after turning west on Baseline Road, continue past
Padua Avenue a short distance to Mills Avenue. Turn north on Mills,
and continue to Mt. Baldy Road. The parking lot is at the northeast
corner of this intersection.
HIKING ROUTE 1
- From the parking area (4523'), pass the gate and hike north up the
road to a large flat area where the road turns left and goes
downhill. Directly to the north is a ridge with a firebreak.
- Go up
this ridge about 50' to a faint trail on the left. Hike along this
trail as it contours around to a saddle (5480') on the northwest side
of bump 5696'.
- Climb northwest up through the brush on a prominent use
trail which becomes another firebreak.
- Continue up this firebreak to
the summit.
SPECIAL CONDITIONS
Although Route 1 has always included portions on private property, HPS'ers have been able to pass with permission. The property is now under
new ownership and that permission is now uncertain. It is suggested that any HPS scheduled hikes take other routes until this issue is resolved.

ROUTE 2

- Gain: 2800'
- Time: 6-7 hours round trip
- Rating: Class 1, strenuous
- Navigation: Difficult
- Leader Rating: "I", normal conditions
DRIVING ROUTE 2
- Take the 210 freeway east to Baseline Road exit in the City of Claremont.
Turn left (west) at the bottom of the off-ramp onto Baseline Road.
- Almost immediately, take the first right (north) onto Padua Ave.
- Go 1.8 miles north on Padua to the intersection with Mount Baldy Rd.
Turn right (northeast).
- Take this road northeast and then north about seven miles to
the USFS Mt. Baldy Vistors Center on the left in Mt. Baldy Village.

Note: Parking at the northeast corner of of Mills and Mt Baldy road is no longer viable. This is now a paid parking lot with a three hour maximum.
Parking in the adjacent neighborhood is also posted and severely restricted.
HIKING ROUTE 2
- From the parking area (4260'),
hike up past the church on Bear Canyon Drive. Bear Canyon Drive is
about 200' south of the Visitors Center. It soon becomes the Bear
Canyon Trail. Continue on this trail about 2 miles to a flat area
just past a stream crossing. This is Bear Flat.
- Continue on this trail about 100' beyond the stream to a large oak
tree on the left. At the left of this tree is a very faint trail
leading down to a gully.
- Follow this faint trail as it goes into a small stand of trees,
crosses a streambed, and starts to contour along the south slope of a
ridge at about 5600' before descending and entering the west fork of
Bear Canyon.
- The trail stays on the right side of the canyon, and grows
increasingly faint. There is an obscure switchback at a large fallen
tree, and the trail continues from about the most uphill point of the
tree. At 6420' the trail comes to an old campsite and disappears.
- Continue up the canyon to the ridge at a point north of bump 6640'+.
Follow a trail south along the ridge around the east side of bump
6930' into the saddle north of Lookout. Continue south up through
brush to the summit.
SPECIAL CONDITIONS
The Forest Service requests that the first 50' of this route off
Bear Canyon Trail not be clipped. The Forest Service does not want
hikers to Mt. Baldy confused by this branching route. Please note that
the Bear Canyon Trail is called the "Baldy Trail" on the
USGS topo.

- Almost immediately, take the first right (north) onto Padua Ave.
- Go 1.8 miles north on Padua to the intersection with Mount Baldy Rd.

Padua Avenue a short distance to Mills Avenue. Turn north on Mills,
and continue to Mt. Baldy Road. The parking lot is at the northeast
corner of this intersection.
HIKING ROUTE 3
- Hike up past the church on Bear Canyon drive. Bear Canyon Drive is
about 200' south of the Visitors Center. It soon becomes the Bear
Canyon Trail.
- Hike up the Bear Canyon trail to the 4800' level. At this
point the trail turns sharply uphill to the east.
Leave the trail, descend and cross the creek to "Erv Bartel" Canyon
(not named on the topo). The
canyon has a bearing 255° true.
- Climb the canyon about 1/4+
mile to where it is blocked by brush. The canyon bottom gradient
decreases significantly as you climb it.
- A clipped trail begins uphill
to the south next to several thin fallen logs. Follow this clipped
trail generally west and up through the brush to the saddle at 5480'
and join Route 1.
This route is commonly used for descent after climbing Route 2.
SPECIAL CONDITIONS
The lower section of this route in the gully is steep and
loose. Caution must be exercised when ascending and descending this
route. Care should be used when crossing the stream after leaving the
Bear Canyon Trail.
NOTE
The peak is in the Sheep Mountain Wilderness Area. Permits are not
required at this time.
HISTORICAL NOTE
In 1926, the physicist A. A. Michelson mounted a system of lights and
mirrors on this peak which, in conjunction with apparatus on Mount
Wilson, 22 miles to the west, permitted measurement of the speed of
light, and in particular, showed that it was independent of the
earth's rotational velocity (i.e. the earth's velocity did not add to
the measured velocity in one direction or subtract from it in the
other). This fundamental constant became a key to Einstein's Theory of
Relativity.
Please report any corrections or changes to the
Mountain Records Chair.
