  4. 4. Welcome to the State Competition of the Road Scholar in Champaign, Illinois. You and your partner are being sent on a field trip to collect data for hydrology or water analysis in southern Illinois. You will be visiting areas near Charleston, Illinois, and Rend Lake State Wildlife Refuge. You are prepared for the trip, with a state highway map [HM] and two topographic maps, Charleston South [CS] and Rend Lake Dam [RLD] . You are currently located in Urbana, Illinois. Consulting your Illinois highway map, you find that the index coordinates for Urbana are _____ [1-HM] . The precise population of Urbana at the date of this map is ____ [2-HM] . Urbana is located in ____ county [3-HM] , and the symbol used for Urbana tells you that it is the _____ [4-HM] of this county. Exam Format
