The northeastern part of Utah in midwinter is very cold. Note the size of the rime ice crystals compared to footprints.The Swelter Shelter petroglyphs are just off the entry road near the National Park Visitor Center.It was our first view of petroglyphs on this trip, so we were excited.Low sunlight brings out some textures in profile, but the high contrast of light and shadow made it difficult to see some images.Other images were very recognizable because of deep carving into the rock face, removing all the surface weathering (desert ‘varnish’) exposing lighter colored underlying sandstone. This appears to be a pronghorn.Extremely dark desert varnish, rich in manganese oxide, provides a high-contrast surface compared to the pale sandstone underneath.Happy to be here.Lizzie booked us an Air B&B that is a converted grain silo!The circular interior spaces were well laid out.That high shelf holds antiques, but that sewing machine looks like my Chairman Mao (a Shanghai-made replica of the Singer Model 15).
