Because this visit was in the summer season and the water was not flowing heavily, one could have hypothesized that the area would consist of smaller pieces of sediment due to the creeks lack of energy great enough to move the large rocks that make up most of the creek bed. The presence of these rocks in the creek suggests that the hydraulic action of Eagle Creek increases significantly during the Spring and Winter months, perhaps due to heavy rainfall and snowmelt that lead to heavy flooding and further erosion.
Eagle Creek and other similar system positioned along the Columbia River Gorge play an important role in the transportation of sediment from mountain ranges to the ocean. Downstream from Punchbowl Falls Eagle Creek meets the Columbia River, suggesting that sediment transportation is present. The eroded walls previously discussed break off and when conditions are right they are eventually pushed downstream, most likely in the rainier months, until they are deposited into the Pacific Ocean by way of the Columbia River.

Punchbowl Falls is an important site in the Columbia River Gorge, drawing thousands of tourists and nature enthusiasts every year. It is vital that visitors recognize the geological importance of places like Punchbowl Falls and Eagle Creek Trail to further promote the conservation of National Forests. With every new natural area being destroyed by pollution and industry, we lose another snapshot into our planet’s
