Table 4. Estimated time and labor efforts for Chuska residents to transport maize to Chaco Canyon based on varying population sizes, carrying capacities, and travel times.

Drennan [132] used loads of 20 and 50 kilograms in his studies of long distance transport. The final weight estimate derives from Malville [131], as reported in Windes and McKenna ([142] p136).

Weight Carried per Person per Trip (kg)	Chaco Population of 2,000: 304,200 kg Maize		Chaco Population of 5,000: 895,700 kg Maize
	Percentage of 10,625 Chuska Population	Percentage of 17,000 Chuska Population	Percentage of 10,625 Chuska Population	Percentage of 17,000 Chuska Population
