McKenzie Pass Summit & Dee Wright Observatory
Highlight • Mountain Pass
A short interpretive trails gives you some information about the landscape around you. The massive lava field was caused by the eruption of the nearby Belknap Crater, but you can hike through lava for miles and miles, since it is mixed with the lava fields caused by The Three Sisters, too. It is a unique landscape and you might feel like you are on the moon. If you want to enjoy a hike besides the observatory here, notice that you need a wilderness permit for the Central Cascades.
There are restrooms at the observatory – a hint for PCT-long-distance hikers. ;)

Plan way more time than you think for this section. There are some old cairns to help you navigate, but those are hard to spot (some become visible when you are already next to them). These are relics from the former 1960s project of "The Desert Trail" that was intended to create a route from Mexico to Canada, but was never finished.

Tips from the Community
To reach Glacier Lake from the north, you'll have to climb Glacier Pass, a 1,000 foot (333m) climb from Moccasin Lake over just under two miles. The trail is easy to follow and has decent, if rocky, footing.

The Pueblo Mountains are a rugged volcanic mountain range located between the town of Fields and Denio. Its defining feature is a 45-degree tilted fault block ridgeline averaging around 7,300 feet. The Oregon Desert Trail leads through this stunning area, mostly cross country with some serious bushwhacking and route finding. Some trees offer shade and the view is amazing.

Lolo Pass is a trailhead along the PCT, but there is not much traffic here. You will find a picnic bench with lovely shade next to the road.

Moss Pass is located below Moss Pass Butte. Several trails - like the Oregon Desert Trail which uses the Fremont National Recreation Trail in this section - and roads cross at this location which has some good spots to pitch a tent. The nearby Moss Spring might be flowing in spring time.

Trip advice is inaccurate. The road from Powers is paved, but only to the saddle on the route shown. (My understanding is that it is paved you turn west at a Y just shy of the saddle, which joins the road into Gold Beach about half way there.) It is decent gravel down to the Agness Jct -- but with lots of rafting traffic in summer. A far more scenic, even bucolic, route is to take the eastern dirt road at the saddle which winds its way down. Just above the Rogue River Trailhead, the road becomes paved and a few miles later joins the main road down from the saddle. Very little traffic on this road.

Agness Saddle, on the paved Agness Road, connects Powers and the Rouge River. It's a key intersection with the gravel forest road to the coast, passing Iron Mountain and following the Elk River.

Situated at McKenzie Pass, Dee Wright Observatory is built entirely of volcanic rock in the shape of a fortress. The lava fields surrounding the observatory span for 100 square miles, offering endless possibilities for other-worldly running scenery! On a clear day enjoy spectacular views of Three Sisters Wilderness, Mount Washington, Mount Jefferson and numerous volcanic craters.
