The Columbia River Basalt Group is the youngest, smallest and one of the best-preserved continental flood basalt province on Earth, covering over 210,000 km 2 (81,000 sq mi) mainly eastern Oregon and Washington, western Idaho, and part of northern Nevada. The basalt group includes the Steen and Picture Gorge basalt formations.

In all, more than 300 individual large (average volume 580 cubic km!) lava flows cover parts of the states of Idaho, Washington, and Oregon. At some locations, the lava is more than 3,500 m thick.

Soft rock is a term that usually refers to a rock material with a uniaxial compressive strength (UCS) less than 20 MPa. This low strength range might be influenced by physical characteristics
Rock mass strength is defined by three parameters including unconfined compressive strength of intact basalt and two others related to the degree of fracturing of the material. Experimental results for elevated temperature extend the applicability of these parameters to the near‐surface environment of Venus.
A study of strength and deformation measurements for basaltic rocks, along with consideration of the influence of fracturing using a rock mass classification system, documents the range of brittle response for basaltic rock masses. Although basalts vary widely in composition and other physical factors, many of the properties of a basaltic rock mass appear to vary within a factor of about 10.

The Stimson and Murray rocks are lithified fine sandstones and coarse silty mudstones, respectively, with varying compressive strengths. Thomson et al. (2013, 2014) illustrated that the energy per unit volume needed to break the bonds of a volume of rock correlates to uniaxial compressive strength (UCS).
Corresponding values for a basaltic rock mass that incorporate the weakening effects of scale are deformation modulus, 10–40 GPa; Poisson's ratio, 0.3; tensile strength, –0.1 to –2.5 MPa

Basalt physical properties such as compressive strength and density are directly linked to their chemistry and constitution; as weathering progresses, basalts gradually become weaker and transition from intact rock to saprolite and ultimately, to soil. Here we quantify the degree of weathering experienced by the Adirondack-class basalts at the Mars Exploration Rover Spirit site by performing
The Columbia Basin Province occupies the entire south-central portion of the state. It is a wide, arid lowland area between the Okanogan Highlands, the southern Cascade Range, the Idaho Rockies, and continues on through much of eastern Oregon and northern Nevada. The area is characterized by steep river canyons, extensive plateaus, and in places, tall and sinuous ridges.

Mafic continental flood basalts form a globally important, but under-characterized CO2 sequestration target. The Columbia River Basalt Group (CRBG) in the northwestern U.S. is up to 5 km thick and covers over 168,000 km2. In India, flood basalts are 3 km thick and cover greater than 500,000 km2.
The largest division in inferred strength between rock types is between Adirondack‐class rocks (including Adirondack, Mazatzal, and Humphrey) and rock and outcrop materials found in the Columbia Hills, a distinction noted previously [e.g., Squyres et al., 2006]. Adirondack‐class rocks are the strongest rocks measured by Spirit and have
