Examine the topographic map above. The locations of 5 different tourist markers are provided (points A-E). During a 100 year flood event, the Yellowstone River will reach a stage of 39 feet. The flood waters are measured from a stream gauge located along the river at 7,686 feet. Which of the tourist markers will survive a 100-year flood? (assume that markers above the flood waters will survive).
