Fjadrargljufur Canyon for #Stunday. Iceland is a gorgeous place for many reasons, but the four canyons we saw (Sigoldugljufur, Múlagljúfur and Studlagil being the other three) were the highlight for me.
Artist Point in #Yellowstone for #Stunday - a view so stunning that Thomas Moran's painting of it helped spur the creation of the National Park system.
Sigöldugljúfur Canyon for #Stunday. You can't see much until you get close to the canyon edge and then it just opens up with all of the waterfalls flowing out of the canyon wall.
