1) Study the geography and geology of the Hetch Hetchy Valley pictured above in a 1977 aerial photograph. Comment on the features that lent the site to dam construction and the existence of a large reservoir.
2) Review the series of slides showing scenes from the construction of the dam. Carefully study the slides you and your group were assigned addressing the questions on the Photo Analysis Guidelines sheet. Be prepared to present your analysis of and questions about each slide as part of a chronological discussion of the dams' construction.
