Our park ranger cum tour guide gives her orientation.
Often visitors to the park look at the size of these doorways and wonder a bout the size of the people who once lived here. An average man was about 5'4" to 5'5" (163cm) tall, while an average woman was 5' to 5'1" (152cm). If you compare them with European people of the same time period, they would have been about the same size. Compared with today, the Ancestral Puebloan's average life span was relatively short, due, in part, to the high infant mortality rate. Most people lived an average of 32-34 years, however some people did live into their 50s and 60s. Approximately 50% of the children died before they reached the age of 5.
Some of the ruins are not in cliffs. They have build roofs on top of them.
