Our children did a stellar job handling the trails of Mosaic Canyon in the morning.
March on Sand Dune
In the afternoon, they marched to the sand dune. All reached the summit without fuss.
The entire roundtrip took us a bit under two hours, factoring in a snack break at the top while taking in the valley view.
Life is great on top of the sand dune!
