The radial Section 2 extends directly behind this view. Methods A 48-channel reflection survey collected 10 m station and 40 m source intervals along a 5 km profile both transverse and radial to Upheaval Dome. Dip-filtered reflection records show clear returns as deep as the base of the Paradox Fm. at 2.5 km. Recording truck at center of two 24-channel spreads.
Main cables are orange, geophone strings are blue.
The arrow points to a reflection from the top of the Paradox Formation at 0.5 s two-way travel time. Note the lower-velocity ground roll. Aerial view NW down Taylor Canyon, just north of Upheaval Dome. The 500 m vertical walls all around the Island in the Sky contributed topographic sidewall reflections to the data. The arrow points to a sidewall reflection having reverse moveout on a shot record, obscuring a Paradox reflection.
