Here is evidence for features from Los Hornos that provides some clues regarding the sizes of houses and stratigraphic level relative to the site datum. Included in this list is a small feature - Feature 70 - that is located in an area north of features 14 and 19 and west of features 21 and 22. It is an odd feature in terms of how small it is.

Depth below the datum may be useful in determining temporal position of some features. You will note the depth of features such as 14 and 19 for example is lower than other features. This is consistant with seriation and chronometric evidence.

House size may be useful in helping shape your ideas about how many people may have lived in this part of Los Hornos at any one time. Keep in mind that estimating populations is tricky. There are several different methods you can use however. One of those is to base the population on area. Raoul Naroll uses a measure of 10 square meters per person as one index of population. This measure is based on identifying the most logical space used for habitation excluding areas that might have served for activities, cooking, etc. James Hill created a formula of 4.55 square meters per person in projecting population at Broken K Pueblo in northern Arizona. This is a very different number than that posed by Naroll but has been shown to be very reasonable in the Southwest. Another method is to estimate the number of households using ethnographic information to assist in estimating a population. If we know for example how many Hopi live within a household, then we can use that figure for estimating population for a prehistoric site. For Pima and Tohono O'odham we know from historic Spanish records that about 4.5 people lived in houses in southern Arizona at the time of contact. This perhaps is a reasonable figure to project for Hohokam populations. We can simply count numbers of rooms and come up with a measure of population size that is relative to how many houses were occupied at any one time. This can allow one to project a relative picture of population growth or decline.
