This collection's many photographs pertaining to rural life and agriculture reflect not only Runyon's own interest in botany, but the importance of agriculture in this region as well. Students can explore how climate and region affect agriculture by comparing images of agriculture and panoramic photographs in the Subject Index of this collection with the many related images comprising the Northern Great Plains collection. What kinds of crops are photographed in each region? How much variety is reflected? What kinds of animals and tools are used in the agricultural practices of each region? What are the similarities and differences between the farms documented in each collection? How do the crops, animals, and farms relate to the landscapes and climates of each region? Students may particularly enjoy searching on snake for images of Joe Guerrero on his Rio Grande Snake Farm.
