The unique soils here support a number of rare plant species, including two that are only found in the Leslie Gulch Drainage. Mule deer, California bighorn sheep, Rocky mountain elk, coyotes, and bobcats all call this area home. Birders can spot chukar, raptors, California quail, and more over these 11,000 acres.

Recreational Activities
Slocum Creek campground has 12 campsites. Picnic tables
are also available. A concrete boat ramp provides Owyhee
Reservoir access for small water craft. Hiking, photography,
plant and wildlife viewing are all popular activities in this
unique canyon setting. Take caution and be prepared for ticks,
rattlesnakes, and extreme weather conditions.
Wildflowers
The talus slopes and unique soils of Leslie Gulch support a
number of rare plant species. Two annual species are found
only in the Leslie Gulch drainage (Packard’s blazing star
Wildlife
Leslie Gulch
In 1965, 17 California
bighorn sheep were
reintroduced into Leslie
Gulch. The herd has
expanded to over 200
animals. Mule deer and
Rocky Mountain elk
are also found in the
area. Bird watchers can spot chukar, numerous song birds,
raptors, California quail, northern flickers, and white-throated
swifts. Coyotes, bobcats, bats, and many reptiles, including
rattlesnakes, also live in Leslie Gulch.
Cultural
Native Americans fished, hunted, and camped along the
Owyhee River in Leslie Gulch 5,000 years before Europeans
came to the area. In 1882, a cattle rancher, Hiram E. Leslie,
was struck by lightning while working in what was then
known as Dugout Gulch; thus, the area was renamed Leslie
Gulch. The original Leslie Gulch Canyon Road long served
as a wagon and mail route between Rockville and Watson.
Today, the town of Watson lies at the bottom of the Owyhee
Reservoir.
Directions to the Site
The site is located east of the Owyhee Reservoir in Malheur
County, Oregon. From Highway 95 in Idaho, go west 8 miles
on McBride Creek Road to Rockville, then 1 mile north to
Leslie Gulch Road and 15 miles west; or take Succor Creek
Road from either Oregon Highway 201 or US Highway 95 to
the Leslie Gulch Road junction.

The most striking features of Leslie Gulch are the diverse
and often stark, towering and colorful geologic formations.
The Leslie Gulch Tuff (consolidated volcanic ash), makes up
the bulk of these formations. It is a rhyolite ash that erupted
from the Mahogany Mountain caldera (a large volcanic
depression which encompasses Leslie Gulch) in a series of
violent explosions about 15.5 million years ago. Much of the
material fell back into the volcano as a gaseous deposit of fine
ash and rock fragments up to 1,000 feet thick. About 100,000
years later, volcanic eruptions from the Three Fingers caldera,
located several miles to the northeast, deposited another layer
of rhyolite tuff in Leslie Gulch. Today, the tuff is beautifully
displayed as steep slopes and vertical, honeycombed towers
carved over time.

Owyhee clover are rare perennials found at a few isolated sites
in the canyon.
