(2004) attribute the Tumalo Creek pumice to Pilot Butte. The volcano's lower southwest flank is covered with white, rhyolitic tephra, which is similar in composition to tephra found at Tumalo Creek Sherrod et al. The lava is composed of 53.5 percent silica and 20 percent aluminum oxide. Pleistocene activity produced highly porphyritic lava with 10 to 15 percent plagioclase phenocrysts reaching diameters of up to 0.20 inches (5 mm). Lava deposited by Pilot Butte has an escarpment of more than 66 feet (20 m). The interior of these lava flows can be explored at Lava River Cave. About 78,000 years ago, similar eruptive activity formed lava flows that surrounded Pilot Butte and filled the Deschutes riverbed, altering the course of the river by redirecting it to form a new channel to the west. ĭuring the late Pleistocene, eruptions at Newberry Volcano produced voluminous basalt lava flows that extended into the area now occupied by Bend and Redmond. The butte's light-colored soil contains some ash from the eruption of Mount Mazama (which formed Crater Lake). The rock has normal magnetic polarity, suggesting that it was laid down after the most recent geomagnetic reversal about 780,000 years ago. Pilot Butte is a Pleistocene cinder cone volcano. The Geographic Names Information System database lists its summit elevation as 4,141 feet (1,262 m) the National Geodetic Survey lists its elevation as 4,142 feet (1,262 m). It sits at the eastern edge of the city of Bend. Pilot Butte is located in Deschutes County, Oregon. The City of Bend launches Fourth of July fireworks from Pilot Butte each year. Most prominent are the Three Sisters, Broken Top, and Mount Bachelor, which are located about 20 miles (32 km) to the west. From the top, the entire city of Bend is visible, as well as several major Cascade peaks. In 2018, the park was the most visited Oregon state park east of the Cascade Mountains. A scenic road also winds up and around the cone. There is also a 1.8-mile (2.9 km) trail around the base of the butte. Pilot Butte itself is a popular hiking destination with two trails to the summit, each gaining about 490 feet (150 m) in elevation. The 114.22-acre (46.22-hectare) Pilot Butte State Scenic Viewpoint, presented as a gift to the State of Oregon in 1928, is a Bend icon. 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. Bend is one of six cities in the United States to have a volcano within its boundaries. It is a cinder cone butte which rises nearly 500 feet (150 m) above the surrounding plains. Each camp site is also cleaned after every departure.Pilot Butte is a lava dome that was created from an extinct volcano located in Bend, Oregon. This park has EXCELLENT restroom and shower facilities all of which are kept clean and well stocked. They found us a place to camp, checked in on us during our stay, kept us supplied with some much needed firewood, AND Vicki put on a Junior Ranger activity for the kids, and Bill set up his telescope so people staying in the park could see Saturn! It was truly awesome!
We were met by the camp hosts, Bill and Vicki, at 9:30pm and I must say, THEY WERE AAAAWESOME!!! My lady and I had been driving for hours with our kids trying to find a place to camp on a, not supposed to be too busy, weekend.
