an uplifted, prehistoric, terrace). This is also a good illustration of strike, the compass orientation of a series of beds' intersection with a normally imaginary horizontal plane. In most cases, a geologist has to use a level- often, the bubble level in a Brunton Compass- to determine precisely where "horizontal" is. In this case, at least to a good approximation, the rocks are beveled horizontally flat, so the lineations of the bedding planes show up as lines. The compass orientations of those lines would be strike.
