This looks like Bryce Canyon National Park, but indeed this area
is known as Mossy Cave, which is outside the main section of
Bryce. As the name implies, Mossy Cave is a wet grotto filled with
moss. In winter the dripping water that feeds the moss turns into
icicles. I went there in summer and thus there is nothing
interesting in Mossy Cave to photograph. Nonetheless, the red
hoodoos in the area under sunset are very beautiful. This area is
also called Water Canyon because there is a stream running across
the canyon, but this is not natural. The river was made to provide
nearby communities with water, and as a result, it washed away
hoodoos along the way.
The last photo was taken in Red Canyon, which is very close to
Mossy Cave.
