I drove up to Rocky Butte this weekend to walk around Joseph Wood Hill Park. Rocky Butte is a 612′ tall extinct volcanic cinder cone, which is part of the Boring Lava Field. In the last ice age, it parted the massive flood waters as Glacial Lake Missoula spilled into the Willamette Valley. Today, it parts the freeways that enter Portland.
I’ve been coming here all my life and have always had an affection for the strange, wonderful, and seemingly useless stone structure at the top. Built in 1937-39, it features an aircraft beacon and panoramic views of the city. On this visit, Portland was very hazy so I plan on returning soon to snap some better pans of the city and the mountains.
Here are my pictures and some diagrams I made:
