A circular feature worn into solid rock by sand, gravel, and stones that have been spun around by water currents.
A cylindrical or hemispherical hold in the bedrock of a stream that is formed from the continual swirling motion of sand and gravel by swirling currents.
A roadway/pavement failure resulting in a depression or hole.
A hole formed in a stream bed by sand and gravel swirled around in one spot by eddies.
a pit or hole produced by wear or weathering (especially in a road surface)
a sharp edged depression in a road (carriageway), usually resulting from the effects of water or weather damage, and stresses caused by heavy vehicles
Landform. A rounded hole in the bedrock of a stream bed, formed by the abrasion of small, water-borne pebbles in the current. See also Tank.
A smooth bowl carved into bedrock by the grinding action of stones whirling around an eddy in a river, such as at a rapids. Many potholes were formed by torrents of glacial meltwater during the Ice Age. The best place to see these along the Ice Age Trail is near the western terminus in Interstate Park — formed when the St. Croix River was much deeper than today.
A bowl-shaped depression in a rock surface that has been carved by the whirling action of stones in a stream bed.
drilling term – a small hole excavated from the surface to a buried utility in order to provide positive verification of its location..
Smooth bowl-shapes ground into rock by small rocks and/or sand swirling in the current of a whirlpool or at the base of waterfalls.
Pits / deep holes formed in the bed of a river by the swirling action of water and stones
A circular depression within a landscape.
A hole generally deeper than wide, worn into the solid rock at falls and strong rapids by sand, gravel, and stones being spun around by the force of the current. In desert country a pothole often collects water during rains and can contain a variety of small freshwater creatures. After rain they can be an important water source for the local wild animals. Care should be taken around potholes to not contaminate or unnecessarily waste the precious water. We try not to walk through them even when they are dry, knowing that the little critters are encapsulated in the dust, just waiting for the next rain storm. See also Tank, Tinaja, and Water Pocket. Potshard See Potsherd. Potsherd (also sherd, shard, or potshard) A piece of a broken ceramic pot. Pouroff A dry waterfall in a drainage.
