Any solid rock exposed at the Earth's surface or overlain by unconsolidated material, such as soil. Often at or near the surface in the BWCA.
a general term for any consolidated rock List of Glossary Terms
Solid layers of rock in the Earth's crust beneath soil.
solid rock underlying gold-bearing gravel.
A general term for consolidated (solid) rock that underlies soils or other unconsolidated materials. See Formation.
The solid, but often fractured and fissured, rock formations that occur beneath soils, unconsolidated sediment deposits or weathered materials. Exposed bare rock is bedrock at the surface. Sediments or weathered material overlying bedrock is sometimes called regolith or overburden.
A general term for the rock, usually solid, that underlies soil or other unconsolidated, superficial material. A British synonym of the adjectival form is solid, as in solid geology.
The solid rock underneath surface soils.
A more or less solid layer of rock found on the surface of the land or below the soil.
The first layer of solid rock found either at or below the land surface.
The continuous, solid rock that underlies soil and loose sediment everywhere.
a general term for the consolidated rock that underlies soils or other unconsolidated surficial materials.
A general term for the rock that underlies the soil and water table. It may hold some water either because it is fractured or is porous.
The solid rock found on the surface of the land or just below the soil
solid rock beneath superficial soil cover and unconsolidated sediments
the solid rock that underlies the soil and other unconsolidated material or that is exposed at the Earth's surface.
Consolidated rock composed of cemented or lithified sediments (such as sandstone, shale, limestone) or crystalline rock such as granite or slate. Underlies all surfical soil, sand, gravel, clay, etc.
The solid rock that underlies all soil, sand, clay, gravel and other loose materials on the earth's surface. Unfractured bedrock is impermeable while fractured bedrock may store and transmit groundwater.
the solid rock underlying the soil and other loose rock material on the Earth's surface.
Originally, this referred to the solid rock bottom of a stream or river. A false bedrock is formed when the feldspar portion of eroded rocks gathers and settles. creating a tough clay or cemented-gravel. The largest quantities of gold are generally recovered within a couple of feet above bedrock.
Continuous solid rock either exposed at the surface of the earth or overlain by a concealing cover of loose material such as that deposited by glaciers, water or wind.
The solid rock underlying unconsolidated surface materials, such as soil.
The solid layers of rock found under sand, dirt or water.
the solid rock underlying the surface materials (soils)
Large quantities of solid rock which form the primary composition of the crust.
Solid rock forming the earth's crust, frequently covered by soil or water.
n. The general term referring to the rock underlying other unconsolidated material, i.e. soil.
Rock substrate that underlies all soil, sand, clay, gravel, and glacial material on the earth's surface.
the layer of rock that lies just beneath the soil at the Earth's surface
cemented or consolidated earth materials exposed on the earth's surface or underlying unconsolidated earth materials, including decomposed and weathered rock and saprolite (soft, completely or partially decomposed rock that has remained in its original site)
The solid rock that underlies all soil or other loose material; the rock material that breaks down to eventually form soil.
Relatively hard, solid rock that commonly underlies softer rock, sediment, or soil; a subset of the basement.
the solid rock beneath the soil and superficial rock. A general term for solid rock that lies beneath soil, loose sediments, or other unconsolidated material.
Any solid rock underlying gold bearing gravels. This is the base rock of the earth and is usually where the larger gold lies.
The solid rock that underlies soil and the regolith or that is exposed at the surface.
A general term for the solid rock that underlies the soil and other unconsolidated material or that is exposed at the surface.
Unbroken solid rock, overlain in most places by soil or rock fragments.
A general term for the rock (e.g., basalt*) that underlies the soil or other unconsolidated, surficial material.
Solid earth materials (limestone, sandstone, shale, etc.) exposed at the land surface or overlain by unconsolidated soil materials such as clay, sand, and gravel.
A general term referring to rock that underlies unconsolidated material.
The solid rock that underlies any unconsolidated sediment or soil. Limestone and sandstone are common types of bedrock in Kansas. Most Kansas bedrock is in formations of Cretaceous age or older.
Rock underlying surface deposits of soil and weathered or broken rock; usually material which is so stiff and strong that it is easily able to carry foundation loads.
A mining term for the unweathered rock below soil and drift cover.
hard-packed rock lying below the Earth's surface; lies in beds or layers; can be variable across geographic space; above bedrock is a layer of broken, weathered rock.
Rock at or near (beneath soil and regolith) the Earth's surface that is solid and relatively unweathered.

Soil with solid rock underneath which provides a foundation on which to construct a building.
Bedrock is the native consolidated rock underlying the Earth's surface. Above the bedrock is usually an area of broken and weathered unconsolidated rock in the basal subsoil. The term implies that the rock lies in beds, or strata.
