Mary Roberts Rinehart,
Through Glacier Park: Seeing America First with Howard Eaton
“ A pass is a bloodcurdling spot up which one's horse climbs like a goat and down the other side of which it slides as you lead it, trampling ever and anon on a tender part of your foot. A pass is the highest place between two peaks. A pass is not an opening, but a barrier which you climb with chills and descend with prayer. A pass is a thing which you try to forget at the time and which you boast about when you get back home. For I have made it clear, I think, that a horseback trip through Glacier Park, across the Rockies, and down the Pacific Slope, is a sporting proposition. ”
