The Kola Superdeep Borehole SG-3 (Russian: Кольская сверхглубокая скважина СГ-3, romanized: Kol'skaya sverkhglubokaya skvazhina SG-3) is the deepest human-made hole on Earth (since 1979), which attained maximum true vertical depth of 12,262 metres (40,230 ft; 7.619 mi) in 1989. [1]
Approximately 0.3 m (1.0 ft) deep on one end of Devils Hole is a small rock shelf of 3.5 by 5 m (11 by 16 ft). The dissolved oxygen of the water is 2.5–3.0 ppm up to around 22 m (72 ft) in depth, though the shallow shelf can have dissolved oxygen levels as high as 6.0–7.0 ppm in June and July.
Voles are seldom seen outside these runways, which enable a faster and safer locomotion and easier orientation. The climbing ability of the common vole is very poor. Underground nests are dug 30–40 cm (12–16 in) deep into the ground and are used for food storage, offspring raising, and as a place for rest and sleep.
Voles are small rodents that grow to 8–23 cm (3–9 in), depending on the species. Females can have five to ten litters per year, though with an average lifespan of three months and requiring one month to adulthood, two litters is the norm. [1]
Eastern meadow voles are active year-round [8] [9] and day or night, with no clear 24-hour rhythm in many areas. [10] Most changes in activity are imposed by season, habitat, cover, temperature, and other factors. Eastern meadow voles have to eat frequently, and their active periods (every two to three hours) are associated with food digestion.
These holes have been previously reported from the region, but their origin remains a mystery,” NOAA Ocean Exploration reported. “While they look almost human made, the little piles of ...
Townsend's vole lives in a burrow system and creates runways among the vegetation in its habitat. The runways are used all year round by successive generations of voles and may be 2.5 to 5 cm (1 to 2 in) deep. [5] In the summer the voles may take advantage of the denser cover available and also move about elsewhere.
A town on North Carolina's Outer Banks issued a public plea to beachgoers about the dangers of digging holes on the oceanfront just hours before a man died at a New Jersey beach when a hole ...
