Natural pyramid

Very near my home is an undeveloped county park that borders Irondequoit Bay. According to official description it is only accessible from the water. I have found a way in over what must be private but also undeveloped and unposted land. It's not easy to get there... it is well hidden.

What is striking about the property is the wild gyrations of elevation as the shoulder of the land tumbles irregularly 175 feet to the bay shoreline. It almost appears the landscape must be the result of something other than nature... but it is nature's work only. I am no geographer so I can only guess what forces formed this land; perhaps it was the last ice age and action of glaciers, but who knows?
