'Bowlder Ca?on', 1874. The Colorado River flowing through Boulder Canyon, (originally Devils Gate Canyon), between Nevada and Arizona, USA. '...we enter the Bowlder Ca?on, cut deep in the metamorphic rocks of foot-hills for seventeen miles, with walls of solid rock that rise precipitously to a height of three thousand feet in many places. A bubbling stream rushes down the centre, broken in its course by clumsy-looking rocks, and the fallen limbs of trees that have been wrenched from the sparse soil and moss in the crevices. The water is discolored and thick'.
