"We continue our journey. In many places the walls, which rise from the water's edge, are overhanging on either side. The stream is still quiet, and we glide along through a strange, weird, grand region. The landscape everywhere, away from the river, is of rock – cliffs of rock, tables of rock, plateaus of rock, terraces of rock, crags of rock – ten thousand strangely carved forms; rocks everywhere, and no vegetation, no soil, no sand. In long, gentle curves the river winds about these rocks."
– John Wesley Powell
"When thinking of these rocks one must not conceive of piles of boulders or heaps of fragments, but of a whole land of naked rock, with giant forms carved on it; cathedral-shaped buttes, towering hundreds or thousands of feet, cliffs that cannot be scaled, and canyon walls that shrink the river into insignificance, with vast, hollow domes and tall pinnacles and shafts set on the verge overhead; and all highly colored – buff, gray, red, brown, and chocolate – never lichened, never moss-covered, but bare, and often polished."
– John Wesley Powell
