Vadose Canyons - Dales Rocks
A large joint exploited beneath major bedding produces a squared canyon with a planar roof, as can be seen in Upper Long Churn Cave. Pools and cascades occur where streams have eroded through weaker zones in the floor such as shale beds, to find a new level.
Vadose zone - Wikipedia
The vadose zone, also termed the unsaturated zone, is the part of Earth between the land surface and the top of the phreatic zone, the position at which the groundwater (the water in the soil's pores) is at atmospheric pressure ("vadose" is from the Latin word for "shallow").
Salt Karst: Mount Sedom diapir - Vignette Collection
Feb 28, 2024 · Vadose canyon is a common feature in subsurface streams in salt (Sedom Cave). Photo: A. Frumkin. Details. A unique, rapidly evolving karst landscape is described below. It develops on salt rock (halite) at such a rate that a human lifetime is enough to observe considerable geomorphic variations.
Kingsdale caves | GeoGuide - Scottish Geology Trust
Low Douk Cave has a meandering vadose canyon draining to a sump pool level with Keld Head (Figure 2.5). It has intercepted several sections of large, abandoned vadose and phreatic passage, one of which terminates at a choke close to the old passages in Rift Pot.
Schoharie Caverns Nature Preserve - National Speleological Society
The initial 2,000 feet of walking passage is primarily a vadose canyon with ceiling heights from 10 to 80 feet. The vadose canyon ends at a sump and the remainder of the cave is accessible only by experienced cave divers. A total of five sumps have been penetrated.
Surrounding a ‘Sunset’ – Dales Rocks
Sunset Hole is a classic vadose canyon passage (SD742759) lying on the limestone bench between Meregill Hole and the massive doline of Braithwaite Wife Hole, which it approaches to the north-east.
Nidderdale caves | GeoGuide - Scottish Geology Trust
Large vadose canyons descend from the main sinks to the head of a long phreatic series, where a staircase of flooded down-loops is interrupted by short sections of vadose cave over loop crests dictated by geological structure.
Ogof Ffynnon Ddu | GeoGuide
Ogof Ffynnon Ddu is the deepest cave system in Britain, and is also one of the most extensive. The complex network of large high-level passages, the exceptionally long vadose streamway, and the many inlets perched high above it, provide an unparalleled record of drainage evolution in the limestone. Introduction

Jul 1, 2022 · Contrary to the majority of caves in the region that have vertical shaft-cave morphology, Chionotrypa is an active vadose canyon, with seasonal presence of snow and ice at the entrance.
NSS Preserve - Schoharie CP - National Speleological Society
The part of the cave enterable without scuba equipment is primarily a single vadose canyon, consisting of 2000 feet of walking passage, with ceiling heights from 10 to 80 feet. Entry does require getting wet.
