Dune Walking

Near the state park, there was a really cool set of dunes that we explored for an hour or few.

A guy saw me timelapsing and came over to chat. He had these rocks - fulgurite pieces - that had come from lightning hitting the dunes. Aparently it's all around the dunes. Lightning hits the dune and melts the sand into glass. He had some really cool pictures of bigger, dendritic chunks that he took.

I"ve never heard it called 'fulgurite' that's funny. I"ve heard it as cristobalite or tridimite - might hae spelled wrong.. but maybe that's just the type of quartz.
