The dark coating on the boulder below you is desert varnish – a concentration of mineral, clay, and organic material that accumulates over time. Prehistoric artists created rock art by exposing the lighter material underneath. But what do . . . — — Map (db m68891) HM

Centuries of scouring floodwaters washed out the arroyo, or gully, beneath this 110-foot (34 meter) petrified log to form Agate Bridge. The stone log, harder than the sandstone around it, resisted erosion and remained suspended as the softer rock . . . — — Map (db m68872) HM
This structure, called Agate House, is a partial reconstruction of an Indian pueblo built here almost ten centuries ago. Indians built dwelling walls like these of petrified wood sealed with mud mortar. Archeologists believe the original eight-room . . . — — Map (db m68689) HM

Approximately 225 million years ago, during the Triassic Period, a floodplain existed here – littered with fallen trees. Periodic flooding buried the logs beneath layers of silt. Over time, silica-laden waters filtered through these deposits . . . — — Map (db m68870) HM
The Rainbow Forest area was the original park head-quarters from 1906 to 1962. In the 1920s, the museum was housed in a tar paper building and instead of a walking trail, a bumpy road wove through Giant Logs. Clearly, many things have changed. But . . . — — Map (db m187257) HM
The petrified wood strewn in the valley below was once encased in the bluffs around you. When erosional forces removed the softer rocks, the petrified wood tumbled and accumulated on the valley floor. Once filled with fallen logs, Jasper Forest was . . . — — Map (db m68871) HM
Did you notice where the trail passed over the faint outlines of the rooms? Over 100 rooms formed a one-story apartment complex surrounding a central plaza in the village. The building materials for the pueblo were blocks of native sandstone, shaped . . . — — Map (db m68887) HM
