Daily Postcard: A cloudy sky recently above Valle Grande. Photo by Irene at Valles Caldera National Preserve. The sky is an integral part of the landscape at the Valles Caldera, whether by day or by night. As part of Art in the Park Day at 2 p.m. on Saturday, April 25, the community is invited to join Santa Fe-based artist Patsy Welch to learn how to paint the clouds above Valles Caldera in watercolors. Cloud painting is a fun and low-stress activity anyone can do. This one-hour program is geared toward children and families. Spots are limited; registration required.
