Figure 2--. Two 24-channel seismic records acquired with Kinestik explosives for refraction interpretation. These data were acquired with geophones located at positions 1 through 24 (station 2+40 on figure 1) and the source at position 0 (left side of figure) and position 25 (right side of figure). Positions 0 through 25 are indicated on the seismic line shown in figure 1. Numbers in italics along the top are the ground stations. Numbers annotated at the top of each trace (below the italicized numbers) give the offset distance from the source in meters. Numbers inset in boxes adjacent to heavy lines indicate the apparent seismic velocities (m/s) interpreted from the first-arrival seismic waves. The 10,168 m/s and 3488 m/s velocities for the long-offset refractions result from refracted waves traveling up- and down-dip, respectively.
