Salmon Falls Creek Reservoir has a multifaceted history intertwined with the region's agricultural development, engineering achievements, and recreational evolution: Construction and Purpose: The Salmon Falls Dam, which created the Salmon Falls Creek Reservoir, was constructed between 1908 and 1910 by the Salmon River Canal Company. Originally, the dam was built to provide irrigation water for farms in the region, addressing the need for a reliable water source for agriculture in the arid climate of southern Idaho. The dam was one of the largest in the world at the time of its construction and was listed on the National Register of Historic Places in 2009 due to its historical significance. Challenges: The dam faced initial challenges due to the porous, lava-rich terrain which allowed water to leak through rather than accumulate in the reservoir as planned. It took 74 years for the reservoir to reach full capacity in 1984, significantly longer than anticipated. Recreational Development: Over time, the reservoir transformed from a primarily irrigation-focused water body to a significant recreational area. Lud Drexler, a pioneer sportsman, played a crucial role in its development for public use, leading to the establishment of Lud Drexler Park in 1981. This park now offers facilities for boating, fishing, camping, and other outdoor activities, making the reservoir a popular spot for recreation in south-central Idaho and Northern Nevada. Fishing and Wildlife: The reservoir is renowned for its fishing, particularly for walleye, making it one of the premier walleye fisheries in Idaho. Various species of fish like brown trout, Chinook and kokanee salmon, yellow perch, among others, are stocked or naturally present, contributing to its status as one of the most plentiful fisheries in southern Idaho. However, there have been concerns about the health of the walleye population due to issues like forage availability and stunted growth from over-abundant predators. Environmental Impact: Efforts have been made to manage the environmental impact, particularly concerning water quality and the ecological balance of species within the reservoir. Actions like adjusting water releases for flood control and managing fish populations have been part of this ongoing effort. Community and Cultural Significance: The area around Salmon Falls Creek Reservoir has historical significance beyond just its physical structures. It served as a trade route for Native American groups between the Snake River Plain and the Great Basin, highlighting its cultural importance before modern development. This history reflects a story of engineering ambition, environmental adaptation, and the transformation of a landscape into a community resource for both agriculture and leisure.

These rocks appears to be a type of **thunder eggs** and **geodes**. Here's why: 1. **Coloration and Banding**: The rock shows a combination of colors, including brown, white, green, and possibly some hints of other colors, which is typical for agates and thunder eggs. The banding pattern is also characteristic of agates, which form in cavities of volcanic rocks. 2. **Translucency**: Some parts of the rock are translucent, which is common in agates due to their chalcedony composition. 3. **Texture**: The rock's texture looks somewhat waxy or glassy, which is typical for agates that have been polished or naturally worn smooth. 4. **Inclusions**: The yellowish or brownish areas could be due to iron oxide or other mineral inclusions, which are often found in agates. Thunder eggs are nodules of agate found in volcanic rocks, and they often have a hollow or partially hollow interior filled with crystals or banded agate.

The geology of the Snake River Canyon near Twin Falls, Idaho, is both fascinating and complex, shaped by millions of years of geological processes. Here's an overview: Formation Volcanic Activity: The canyon's history is closely tied to the volcanic activity of the Yellowstone hotspot. Around 17 million years ago, the hotspot began to influence the region, leading to extensive volcanic activity. The Columbia River Basalt Group, massive lava flows, covered much of the area, including where the Snake River now flows. Erosion: The Snake River Canyon itself was primarily carved out by the erosive power of the Snake River. However, the initial shaping was also influenced by the uplift of the region, which began around 10 million years ago due to the tectonic forces associated with the Basin and Range Province. Geological Features Basalt Cliffs: The canyon walls are composed largely of basalt from the Columbia River Basalt Group eruptions. These layers of basalt, which can be seen in the various cliffs and outcrops, were formed by multiple volcanic events, each layer representing a different flow. Perrine Bridge: A significant geological feature near Twin Falls is the natural bridge known as the Perrine Bridge, which spans the canyon. While the bridge itself is man-made, it's built where the natural geology of the canyon narrows, showcasing the canyon's depth and the rugged basalt formations. Craters of the Moon: Although not directly part of the canyon's geology, the nearby Craters of the Moon National Monument provides a glimpse into the volcanic past that shaped the region, with its lava fields and cinder cones. Erosion and Modern Geology River Erosion: The Snake River continues to erode its path through the canyon, carrying sediment downstream. This ongoing process has resulted in the canyon's deep, V-shaped profile, especially notable around Shoshone Falls, sometimes called the "Niagara of the West." Sedimentation: The river also deposits sediments, influencing the canyon's floor. Over geological time, these deposits have contributed to changes in the river's course and the canyon's shape. Tectonic Uplift: Part of the Snake River Plain is still rising due to tectonic movements, which affects the river's gradient and, consequently, the erosion patterns in the canyon. Recent Geological Events Earthquakes: The region experiences seismic activity due to its location near the edge of the Basin and Range Province, which can influence the canyon's geology through minor shifts or larger earthquakes. Human Impact: Human activities, including dam construction (like the Shoshone Falls Dam), have altered the natural flow and erosional patterns of the river, affecting the canyon's geological evolution. The Snake River Canyon is a dynamic geological feature where volcanic, tectonic, and fluvial processes continue to shape the landscape, offering a rich field for geological study and appreciation.

Kuna Caves are lava tubes found south of Kuna, Idaho. There is currently one publicly known entrance to the cave, an opening in the ground with a caged ladder leading down into the cave. Background The caves are about 50 feet (15 m) deep and run about a quarter mile north and around 1,000 feet (300 m) south from the entrance. The southern portion of the cave requires you to crawl through a trench dug out of the clay floor of the cave leading to a small space approximately 4 feet (1.2 m) long by 3 feet (0.91 m) wide by 3 feet (0.91 m) high in which you can turn around to return to the main cavern.[1] Though according to locals, at one time the system had been much larger and was composed of multiple caves, even stretching to the Snake River, before the United States Army Corps of Engineers blocked it off by detonating dynamite collapsing a portion of the cave.[2] A logbook was placed deep in the North end of the cave for people to sign in 2018. Although the entrance has a ladder to get down into the cavern, it is not maintained. The short road leading to the cave is unmaintained, often very muddy, and the cave itself is littered with trash and graffiti. The interior temperature of the cave hovers around 56 °F (13 °C) year round.[3] The official Bureau of Land Management stance on the cave is that it should not be visited by the general public.

A cave or cavern is a natural void under the Earth's surface. Caves often form by the weathering of rock and often extend deep underground. Exogene caves are smaller openings that extend a relatively short distance underground (such as rock shelters). Caves which extend further underground than the opening is wide are called endogene caves. Speleology is the science of exploration and study of all aspects of caves and the cave environment. Visiting or exploring caves for recreation may be called caving, potholing, or spelunking. Formation types The formation and development of caves is known as speleogenesis; it can occur over the course of millions of years. Caves can range widely in size, and are formed by various geological processes. These may involve a combination of chemical processes, erosion by water, tectonic forces, microorganisms, pressure, and atmospheric influences. Isotopic dating techniques can be applied to cave sediments, to determine the timescale of the geological events which formed and shaped present-day caves. It is estimated that a cave cannot be more than 3,000 metres (9,800 ft) vertically beneath the surface due to the pressure of overlying rocks. This does not, however, impose a maximum depth for a cave which is measured from its highest entrance to its lowest point, as the amount of rock above the lowest point is dependent on the topography of the landscape above it. For karst caves the maximum depth is determined on the basis of the lower limit of karst forming processes, coinciding with the base of the soluble carbonaterocks. Most caves are formed in limestone by dissolution. Caves can be classified in various other ways as well, including a contrast between active and relict: active caves have water flowing through them; relict caves do not, though water may be retained in them. Types of active caves include inflow caves ("into which a stream sinks"), outflow caves ("from which a stream emerges"), and through caves ("traversed by a stream"). Speleothems in Hall of the Mountain King of Ogof Craig a Ffynnon, a solutional cave in South Wales. Solutional cave Solutional caves or karst caves are the most frequently occurring caves. Such caves form in rock that is soluble; most occur in limestone, but they can also form in other rocks including chalk, dolomite, marble, salt, and gypsum. Except for salt caves, solutional caves result when rock is dissolved by natural acid in groundwater that seeps through bedding planes, faults, joints, and comparable features. Over time cracks enlarge to become caves and cave systems. The largest and most abundant solutional caves are located in limestone. Limestone dissolves under the action of rainwater and groundwater charged with H2CO3 (carbonic acid) and naturally occurring organic acids. The dissolution process produces a distinctive landform known as karst, characterized by sinkholes and underground drainage. Limestone caves are often adorned with calcium carbonate formations produced through slow precipitation. These include flowstones, stalactites, stalagmites, helictites, soda straws and columns. These secondary mineral deposits in caves are called speleothems. The portions of a solutional cave that are below the water table or the local level of the groundwater will be flooded.

A cave or cavern is a natural void under the Earth's surface. Caves often form by the weathering of rock and often extend deep underground. Exogene caves are smaller openings that extend a relatively short distance underground (such as rock shelters). Caves which extend further underground than the opening is wide are called endogene caves. Speleology is the science of exploration and study of all aspects of caves and the cave environment. Visiting or exploring caves for recreation may be called caving, potholing, or spelunking. Formation types The formation and development of caves is known as speleogenesis; it can occur over the course of millions of years. Caves can range widely in size, and are formed by various geological processes. These may involve a combination of chemical processes, erosion by water, tectonic forces, microorganisms, pressure, and atmospheric influences. Isotopic dating techniques can be applied to cave sediments, to determine the timescale of the geological events which formed and shaped present-day caves.[4] It is estimated that a cave cannot be more than 3,000 metres (9,800 ft) vertically beneath the surface due to the pressure of overlying rocks. This does not, however, impose a maximum depth for a cave which is measured from its highest entrance to its lowest point, as the amount of rock above the lowest point is dependent on the topography of the landscape above it. For karst caves the maximum depth is determined on the basis of the lower limit of karst forming processes, coinciding with the base of the soluble carbonate rocks. Most caves are formed in limestone by dissolution. Caves can be classified in various other ways as well, including a contrast between active and relict: active caves have water flowing through them; relict caves do not, though water may be retained in them. Types of active caves include inflow caves ("into which a stream sinks"), outflow caves ("from which a stream emerges"), and through caves ("traversed by a stream").[7] Speleothems in Hall of the Mountain King of Ogof Craig a Ffynnon, a solutional cave in South Wales. Solutional cave Solutional caves or karst caves are the most frequently occurring caves. Such caves form in rock that is soluble; most occur in limestone, but they can also form in other rocks including chalk, dolomite, marble, salt, and gypsum. Except for salt caves, solutional caves result when rock is dissolved by natural acid in groundwater that seeps through bedding planes, faults, joints, and comparable features. Over time cracks enlarge to become caves and cave systems. The largest and most abundant solutional caves are located in limestone. Limestone dissolves under the action of rainwater and groundwater charged with H2CO3 (carbonic acid) and naturally occurring organic acids. The dissolution process produces a distinctive landform known as karst, characterized by sinkholes and underground drainage.

Succor Creek State Natural Area lies in a deep, rocky canyon and is a remote haven for rock hounds and wildlife watchers. Limited souvenir collecting by rock hounds is permitted in the park. A rough 15 mile dirt road leads from Oregon 201 to the park, which has primitive camping and day-use areas along both side of the creek. No water is available. The Succor Creek Bridge is open to vehicles for access to the campsites on the east side of the creek (right/south of the bridge). The road to the left/north of the bridge is not safe for vehicular travel. There are no pay phones or cell phone services at the Park. Staff and Staff Volunteers are not stationed at this site. This is a remote recreational experience, please prepare accordingly. Year-round camping (first-come, first-served) Four primitive sites on the west side of the creek 14 primitive campsites on the east side of the creek Vault toilet No water available
