We were a bit short on time so we only made it as far as the lower Emerald Pool which was a bit of a non event. However the cliff face over the pools showed great colouring from the spring water seeping through the rocks.
Zion NP is the only one of the parks we visited where Terry Tourist goes into the canyon itself rather than looking down into the canyon from above. Consequently, the vast majority of the shots I took were in portrait mode.
