Pilot Butte is a lava dome that was created from an extinct volcano located in Bend, Oregon. It is a cinder cone butte which rises nearly above the surrounding plains. Bend is one of six cities in the United States to have a volcano within its boundaries. The other examples are Mount Tabor in Portland, Oregon, Jackson Volcano in Jackson, Mississippi, Diamond Head in Honolulu, Glassford Hill in Prescott Valley and Pilot Knob in Austin, Texas. The Pilot Butte State Scenic Viewpoint, presented as a gift to the State of Oregon in 1928, is a Bend icon. Pilot Butte itself is a popular hiking destination with two trails to the summit, each gaining about in elevation. There is also a trail around the base of the butte. A scenic road also winds up and around the cone. In 2018, the park was the most visited Oregon state park east of the Cascade Mountains. From the top, the entire city of Bend is visible, as well as several major Cascade peaks. Most prominent are the Three Sisters, Broken Top, and Mount Bachelor, which are located about to the west. The City of Bend launches Fourth of July fireworks from Pilot Butte each year. Geology Pilot Butte formed approximately 188,000 years ago from the eruption of a volcanic vent. The rock has normal magnetic polarity, implying that it was laid down after the most recent geomagnetic reversal about 780,000 years ago. The butte's light-colored soil contains some ash from the eruption of Mount Mazama (which formed Crater Lake). Ecology The most common tree on Pilot Butte is Western juniper, which is sometimes parasitized by witches' broom mistletoe. Also abundant are sagebrush and the similar plants bitterbrush and rabbitbrush. The invasive species cheatgrass is likely the most common grass on the butte. Wildflowers that appear include sand lily, rock cress, penstemon, paintbrush, buckwheat, yarrow, blazing star, mariposa lily, lupine, and monkeyflower. Ponderosa pine and red currant can also be found. Birds and deer feed on some of the plants, and some animals use snags as shelter. History Pilot Butte was named in 1851 by Thomas Clark, leader of the first party of European settlers to camp on the future site of Bend. The Clark wagon train approached the area from the east after recovering from the Clark massacre. The butte was gifted to State of Oregon as a public park in 1928 by
