Lunch was at one of the 7 sites high above the lake with a view of the lake and a cinder cone to the South. After North Matthieu Lake we rejoin the PCT and climb to South Matthieu Lake. The views at this point are outstanding. To the west are large lava flows. You can see where one flow was over the top of an older flow.
North Sister occupies the South West view.
A short trail to the East leads to a view of the Central Oregon High Desert. The walk back via the PCT was quite spectacular. The trail followed along the West side of a ridge with views of the Cascade Peaks and of course the Lava Beds. Total distance hiked was about 6 miles, one of the more interesting 6 miles we've hiked. I'd recommend this short trip to anybody that can get to McKenzie Pass in the Oregon Cascades.
