Abstract : Measurements on Operation UPSHOT-KNOTHOLE Shot 7 consisted of ground-level pressures on a ridge to the west of the shot point, the same ridge that was instrumented on Shot 5 of TUMBLER-SNAPPER. Special attention was paid to measuring pressures farther fore and aft of the ridge than before and increasing the number of gages near the crest. Previous observations were confirmed in that pressures on the foreslope were higher (spiked waveforms) and those on the back slope lower (rounded waveforms) than would have been predicted at the same distance over flat terrain. Enough detail was obtained to show that these effects were caused by a compression wave from the initial upslope of the ridge and a rarefaction wave from the downslope at the crest of the ridge.
