The south-facing slopes above and to the north of Dillacort Creek, Klickitat River drainage............April 3, 2011. The lower portion of the slope is Columbia Land Trust property while the upper slope is part of the Klickitat Wildlife Area.

Dillacort Canyon is a large canyon that descends from the northern slopes of Stacker Butte (Columbia Hills), generally trending northwestward until the last mile or two where it flows mostly westward. The section hiked was the lower portion which enters the Klickitat River from the east about 6 miles north of Lyle, WA. Access is from a gravel pullout on the east side of Washington Highway 142 at the mouth of Dillacort Canyon. The lower two miles of the Canyon are mostly on Columbia Land Trust, Klickitat Wildlife Area and Department of Natural Resources (Southeast Region) lands. Signs at the trailhead request hikers to obtain written permission to enter the Columbia Land Trust property along the east side of the highway (See the link above.). It probably doesn't hurt to contact the other two land managers if you plan to hike here.

The north-facing slopes on the south side of the canyon are largely coniferous. The south-facing slopes of the canyon are largely open with occasional Oregon white oak forests. Quite a bit of poison oak can be found under the oaks as well as out in the open, so caution should be exercised especially when trying navigate through the patches of woods. The canyon slopes are very steep (30-40 degrees) with poor footing. The soil is mostly clay with some patches of basalt talus. Once dried, the clay soil will be difficult to walk on when traversing the steep side slopes. The area that this hiker covered appeared to be fairly natural with only some evidence of cattle grazing during the past one or two seasons. Views are southwest down the Klickitat River, north along the Klickitat River and south from the highest slopes towards Stacker Butte. Because it was cloudy during my previous visit high on the ridgeline, it is currently unknown if there is a view towards Mt. Adams. The view east is dominated by the western rim of High Prairie.

The route of this visit was along the old 4WD road which follows the southern shore of the creek. Several spur roads proceed downhill from the old road to benches along the creek. The road is mostly through a mix of oak and coniferous forests (ponderosa pine and Douglas fir).
