Sand trees

I was long curious about the mechanics of these flow patterns.

According to experts, as groundwater flows onto the beach toward low spots, it picks up sand grains and carries them along while eroding increasingly deeper channels that converge into a reverse dendritic pattern with water and sand flowing from the branches toward the trunk.

These weird shaped patterns, photographed during sunsets - twilight, remind me of ghost trees and haunted forests.

My obsession with trees seems to be following me on the beach as well..!
