64-700: The Lava River Cave near Bend, Oregon , is part of the Newberry National Volcanic Monument , which is managed by the United States Forest Service . At 5,211 feet (1,588 m) in length, the northwest section of the cave is the longest continuous lava tube in Oregon . While the cave's discovery in 1889 was officially credited to a pioneer hunter, the presence of obsidian flakes near the cave has led archaeologists to conclude that Native Americans knew about

128-496: A fordable crossing point of the river, where it ran through a bend. An 1870s ranch popularized the name "Farewell Bend", with the post office later distinguishing the area as Bend. It was incorporated as a city in 1905, starting off as a logging town. In 1910, Mirror Pond was created as a dammed river reservoir to provide energy. In 1950, the two major logging companies were consolidated due to depleted timber, causing an economic drop. In later decades, it experienced rapid growth as

The harvestmen within the cave are Taracus marchingtoni , a newly described species endemic to the region. There are also mice and bats that live in the cave year around. The cave's bat population is relatively small and the bats are very shy so visitors rarely see them. In fact, bats usually remain in hibernation until July, and when active they are nocturnal so they are asleep during

The smooth walls are remarkably symmetrical so sounds echo in the huge chamber. In this section, remnants of the ancient lava flow's current can be seen molded in the tunnel walls. They appear as rounded over-hanging shelves and lateral markings etched in

576-404: A large boulder pile. Since freezing temperatures occurs only near the mouth of the cave, most rock-falls are in this area. To get down the rock pile, visitor must descend 126 steps with handrails for safety. At the bottom of the stairs is a large cool chamber where winter ice fills cracks in the floor and ice stalactites often cling to the ceiling until June. After a short walk, the ceiling reaches

There are numerous public art displays , including the Roundabout Art Route tour of outdoor sculptures throughout

At the Sand Garden, the constant dripping of water has carved spires and pinnacles in the sand. Since it takes hundreds of years to build these delicate sand forms, the Forest Service has fenced off the garden area to protect it. The 2,211 feet (674 m) of cave trail beyond

1152-401: Is the longest known uncollapsed lava tube in Oregon. The other section extends 1,560 feet (480 m) southeast from the entrance. This section runs toward the source of the flow so it has a slight uphill grade. This section is not open to the public because of loose rocks in the ceiling. The mouth of the cave is at an elevation of 4,500 feet (1,400 m) above sea level. At its deepest point

Todd sold this to John Sisemore in 1881, who applied for a post office in 1886. Because the name "Farewell Bend" was already in use, it was shortened to "Bend" by the United States Post Office Department . Constructed in May 1901, the Pilot Butte Development Company 's little plant

1344-462: The Sand Garden , located about 3,000 feet (910 m) from the entrance. Here the floor of the cave is covered with sand. The sand was carried into the cave by dripping water. The sand is fine volcanic ash from the eruption of Mount Mazama 6,600 years ago. Rain and melting snow carried the ash down from the surface through cracks in the rock and deposited it on the floor of the cave one grain at

2112-476: The cave is 4,350 feet (1,330 m) above sea level. The cave's entrance appears as a large hole in the ground. At its mouth, the entrance trail drops suddenly over a jumble of volcanic rocks. This area is known as the Collapsed Corridor . It is the result of ground water freezing in rock cracks in the ceiling. Loosened rocks eventually fall. Over the centuries, the fallen rocks have accumulated into

2176-513: The cave leaving hot gases trapped in the interior of the tube. These gases re-heated the lava tube causing the tunnel walls to re-melt. As re-melted rocks cooled, the walls were left with a shiny, glazed surface. There are also volcanic stalactites in this area of the cave. These formations are sometimes called lavacicles . They are found in two forms. Some are hollow cylindrically shaped soda straws, formed by escaping gases. The others are cone shaped drip pendants formed when re-melted lava dripped from

The source is believed to be near Mokst Butte southeast of the entrance. The same volcanic flow that formed the cave underlies much of the Bend area and almost reaches Redmond, Oregon . However, the specific vent that created the cave has been buried by several younger flows. The Lava River Cave
