 ROAD LOG 



DE KALB TO STARVED ROCK STATE PARK 

 SATURDAY, MAY 13, 1972 



Leaders: Charles Collinson, Matthew J. Avcin, Rodney D. Norby, Glen K. Merrill 



Meet in parking lot east of Northern Illinois University Field House, 

 where participants needing transportation can find rides. When filled, auto- 

 mobiles should proceed independently to the main parking lot on the river 

 bottom at Starved Rock State Park. DO NOT TRAVEL IN CONVOY ON THIS LEG OF 

 THE TRIP! DRIVE SAFELY I 



Mile 00.00 on the road log will begin at the intersection of U.S. 

 Interstate 80 and Illinois Route 23 just north of Ottawa-^0 miles almost 

 due south of De Kalb. Log mileage given is only approximate. To leave 

 De Kalb, leave the parking lot by turning right (south) on University Circle 

 Drive. University Circle swings eastward near the University School and 

 joins Carroll Avenue approximately a block and a half to the east. Turn 

 right (south) on Carroll Avenue and go 1/2 block on Lincoln Highway (U.S. 

 Route 30). Turn left (east) on Lincoln Highway. Travel approximately 1/2 

 mile to its junction with Illinois Route 23. Turn right (south) on Route 23, 

 which will take you directly to Ottawa. See route map and time schedule 

 on inside front cover. 



Checkpoints, measured from the south city limits of De Kalb, are: 

 U.S. Route 30 at 10 miles, village of Victor at 18 miles, junction with 

 U.S. Route 34 at 22 miles, junction with U.S. Route 52 at 32 miles, and 

 junction with U.S. Interstate Route 80 at 40 miles (start road log at cross- 

 over with Interstate 80) . 



Virtually the entire route to Ottawa will be made over Pleistocene 

 (Wisconsinan) groundmoraine . Only two morainal ridge belts will be crossed. 

 The first, the northeast-southwest trending Shabbona-Arlington-Mendota 

 morainal complex, will be encountered about 4 miles south of De Kalb (near 

 the junction of Route 23 and the Milan road) . It accounts for the undula- 

 ting topography for the next 6 miles. Sixteen miles south of De Kalb, the 

 Farm Ridge Moraine trends northeast-southwest and forms a four -mile wide 

 belt which extends to the village of Victor. South of the Farm Ridge Moraine 

 to the Illinois Valley at Ottawa, the route is on the flat plain of Lake 

 Ottawa, an upland area flooded by the glacial meltwater from the Kankakee 

 Flood. The flood resulted about 14,000 years ago when glacial ice from 

 the Erie glacial lobe blocked a discharge route to the Wabash Valley on the 

 southeast and meltwater from the Erie, Lake Michigan, and Saginaw glacial 

 lobes concentrated in the drainage systems of the Kankakee and Illinois 

 Rivers .
