Mace Glen Canyon is a sixty yard cleft which was once a river bed and now converted into a road. However, original planners failed to comprehend that taking advantage of this geographical feature might also lead to some complications. When heavy rains descended upon Denbrook the road quickly became a river again.
In order to solve this problem, engineers raised the road twenty feet off the earth and created some aqueducts to siphon off storm water. Some spelunkers like to explore these aqueducts, which are said to cut through some natural underground caverns, however at least seven spelunkers have died when they were caught in the floodwaters of unanticipated storms.
