Boyd Cave
Boyd Cave is a lava tube within Deschutes County, Oregon, of the United States. The cave is within Deschutes National Forest and is located on the northern flank of Newberry Volcano near the city of Bend. Geology Boyd Cave is between 75,000 and 400,000 years old. Similar to Skeleton Cave, it is a well preserved lava tube with little interior collapse and exhibits pahoehoe flow structures on its walls, ceiling and floors. Unlike Skeleton Cave, the roof of Boyd Cave is very thin at less than 3 feet thick in some places. The cave is entered via a stairway through a 10 foot diameter skylight. The cave is mostly walking passage except for a small 10 foot long hand-and-knees crawl about two thirds of the way into the cave. Boyd Cave is a part of the same lava flow as Skeleton Cave and trends toward Skeleton's Bear Passage. History The cave is one of several caves off China Hat road. The cave was originally known to cavers of the region as Coyote Butte Cave after the nearby cin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Caving
Caving – also known as spelunking in the United States and Canada and potholing in the United Kingdom and Ireland – is the recreational pastime of exploring wild cave systems (as distinguished from show caves). In contrast, speleology is the scientific study of caves and the cave environment.Caving in New Zealand (from Te Ara: The Encyclopedia of New Zealand, Accessed 2012-11.) The challenges involved in caving vary according to the cave being visited; in addition to the total absence of light beyond the entrance, negotiating pitches, squeezes, ...

Lava Tubes
A lava tube, or pyroduct, is a natural conduit formed by flowing lava from a volcanic vent that moves beneath the hardened surface of a lava flow. If lava in the tube empties, it will leave a cave. Formation A lava tube is a type of lava cave formed when a low-viscosity lava flow develops a continuous and hard crust, which thickens and forms a roof above the still-flowing lava stream. Tubes form in one of two ways: either by the crusting over of lava channels, or from pāhoehoe flows where the lava is moving under the surface. Lava usually leaves the point of eruption in channels. These channels tend to stay very hot as their surroundings cool. This means they slowly develop walls around them as the surrounding lava cools and/or as the channel melts its way deeper. These channels can get deep enough to crust over, forming an insulating tube that keeps the lava molten and serves as a conduit for the flowing lava. These types of lava tubes tend to be closer to the lava er ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Oregon High Desert Grotto
The Oregon High Desert Grotto (or OHDG) is an American caving club, known as a Grotto. It is affiliated with the National Speleological Society. OHDG is involved with caving and conservation efforts in central Oregon and beyond, including the Oregon Caves National Monument, the Lava Beds National Monument in northern California, and caves in western Idaho and southern Washington. Members of the Grotto have worked with the Department of State Lands and received a participation award from state leaders for their volunteer work. In 2013, the Grotto was recognized by Region 6 of the United States Forest Service for various volunteer hours working with caves and bats. They received the R6 Volunteers and Service and Program Award. History The Oregon High Desert Grotto was first created in 1989 by Dan Best. It lasted only a year before complications terminated the Grotto. In late 1995, the OHDG was reformed by the new founding member Ric Carlson, who was at the time an employee of ...

USFS
The United States Forest Service (USFS) is an agency of the U.S. Department of Agriculture that administers the nation's 154 national forests and 20 national grasslands. The Forest Service manages of land. Major divisions of the agency include the Chief's Office, National Forest System, State and Private Forestry, Business Operations, and Research and Development. The agency manages about 25% of federal lands and is the only major national land management agency not part of the U.S. Department of the Interior, which manages the National Park Service, the U.S. Fish and Wildlife Service, and the Bureau of Land Management. History The concept of national forests was born from Theodore Roosevelt's conservation group, Boone and Crockett Club, due to concerns regarding Yellowstone National Park beginning as early as 1875. In 1876, Congress formed the office of Special Agent in the Department of Agriculture to assess the quality and conditions of forests in the United States. ...

Cinder Cone
A cinder cone (or scoria cone) is a steep conical hill A conical hill (also cone or conical mountain) is a landform with a distinctly conical shape. It is usually isolated or rises above other surrounding foothills, and is often of volcanic origin. Conical hills or mountains occur in different shap ... of loose pyroclastic fragments, such as volcanic clinkers, volcanic ash, or scoria that has been built around a volcanic vent. The pyroclastic fragments are formed by explosive eruptions or lava fountains from a single, typically cylindrical, vent. As the gas-charged lava is blown violently into the air, it breaks into small fragments that solidify and fall as either cinders, clinkers, or scoria around the vent to form a cone that often is symmetrical; with slopes between 30 and 40°; and a nearly circular ground plan. Most cinder cones have a bowl-shaped Volcanic crater, crater at the summit. Mechanics of eruption Cinder cones range in size from tens to hundreds of meter ...

China Hat (Oregon)
China Hat is a volcanic butte __NOTOC__ In geomorphology, a butte () is an isolated hill with steep, often vertical sides and a small, relatively flat top; buttes are smaller landforms than mesas, plateaus, and tablelands. The word ''butte'' comes from a French word mea ... on the southeastern flank of Newberry Volcano in Deschutes County, Oregon, Deschutes County, Oregon, United States. It is a rhyolite, rhyolitic Lava dome, dome dating from the age of the Middle Pleistocene. Both China Hat and nearby East Butte are covered by Mazama Member, Mazama Ash and Newberry Ash. Although China Hat is often thought of as a side vent of Newberry Volcano less than ten miles away, it is estimated to be older than first formation of the Newberry Caldera, 780,000 thousand years old versus 500,000 years ago and is on the western edge of a series of high lava plains eruptions derived from a tongue of the same mantle plume that fuels the Yellowstone Caldera China Hat Road, named after ...

Skeleton Cave (Oregon)
Skeleton Cave is a lava tube within Deschutes County, Oregon, of the United States. The cave is within Deschutes National Forest and is located on the northern flank of Newberry Volcano near the city of Bend. The cave is between 75,000 and 400,000 years old. Origin of the name The cave was first documented by American settlers circa 1924, although a stick was found inside the cave with pencilled markings showing visitation from 1894. Perhaps on that same visit, an illegal moonshiner's still was found inside the cave. At one time the lava tube may have been referred to as Bone Cave but it received its current moniker as Skeleton Cave from Phil Brogan who observed many assorted pieces of skeletons within. One theory put forth by Dr. James W. Gidley, a scientist from the National Museum, claimed all the fossils fell into the cave from cracks in the ceiling created by earthquakes. Gidley believed this because he couldn't fathom why an animal would crawl all the way into the cav ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
