The Johnson Canyon trail starts out on a series of catwalks suspended off the gorge wall.  It makes for a unique perspective on the stone carving of the creek below.  There
was even a walkway through a tunnel cut by the creek long ago.  We stood in the spray.  Upstream we came upon these pools they call inkpots.  The spring water comes up in the bottom of shallow pools and creates all sorts of odd currents that move the fine glacier flour around in amazing patterns.
Cool.
