Gorges, many cut through solid rock, divide mountain ranges all over the earth. Today, where rivers run, are waterways which evolutionary geologists call ‘discordant drainage systems’ because they do not fit the deep time model of millions of years as expected by naturalistic slow and gradual erosion patterns. However, the evidence of discordant water erosion fits erosion patterns caused by very rapid and catastrophic processes as with gorges smoothed and carved by sudden and massive water run offs.
Such processes were observed at Mount Saint Helen’s when valleys over a mile long were formed in less than a year. Today this gorge is called the “Little Grand Canyon” due to the Arial similarities of the two canyons.
