there are three sets of images, the first is the view looking into the step house from the South-East entrance. The second set are three examples of rock art and the last is a panorama of the scene looking from the landing directly below the star rock art pictographs.
The Mesa Verde Step House has several types of images, the first two shown are examples of petroglyphs and the third is the pictograph stars on the ceiling.
The numbers (readings) are altitude (degrees above + and below - the horizon) over/ Azimuth (Magnetic) the 0/99 is the east horizon as it meets the south wall. This is where the first picture was taken at noon. The 5/56 is five degrees above the horizon, the rock true bearing would be 67, the Summer Solstice (SS) sunrise location would be behind the rock seven degrees. The WS, Winter Solstice is at 120 degrees true (109 magnetic) and would be visible from the newer construction for only an hour or so during the winter.
The Step House at Mesa Verde winter sunlight is going to vary from limited to not at all. The pit house area will have no sunlight from November to January and minimal sunlight from September to March. The area below the stars (later generations) will receive only a few hours per day of sunlight from October to February and less than a half day of sunlight from April to August. There were no obstructions to create any interesting light effects for the summer months and perhaps around the winter solstice there could be a brief sunlight feature.
The Star pictographs were in the shadow at the time of day of observation from noon to three at summer solstice. I could only see three, though other observers could see six or seven stars. Pictures at other time of day and perhaps the use of Photoshop or DStretch could bring out more detail. Star update and possible constellations??
