My wife and I will be visiting my step-daughter and our older grands in the near future. Since we will have some time to ourselves during the trip while the girls are at work, we're considering a little bit of rock-hunting (not quite -hounding, a bit more casual). Last year, I know that blueyblue had suggested areas around Ocean Drive and Cherry Grove beaches for obsidian tears. We would appreciate any and all advice about possible locations within a short drive, to spend some time in nature and to look for some cool rocks.
Thanks in advance!

LazerFlash I have never heard of obsidian anywhere along the South Carolina coast and there was no volcanic activity around there. I live in SC and have only found a few small fossil turtle shells and small shark teeth around North Myrtle Beach which is were Ocean Drive and Cherry Grove beaches are. I have some friends there who have found nice fossil shark teeth and bison teeth, etc. behind their apartment complex around the intracoastal waterway as there is a large section of it that has been dug out when it was constructed. It is so built up around there that access is a problem. Generally I look for fossils a lot further south from Folly Beach in Charleston through Edisto Island which is about thirty miles below Charleston. Most of the meg teeth that are found are found by people diving the coastal rivers and bays. Most rock along the South Carolina coast has been brought in from the inland granite quarries which are in the north and western parts of the state.

The strand has changed . We used to find them in parking lot areas around Ocean Drive and Cherry Grove beaches. I remember a rental beach house that had them everywhere in the drive-under garage.
After rereading that snippet, I'm thinking that the obsidian was not of local original and was probably imported as fill of some kind.

Probably some kind of fill under that beach rental house but I don't know why anyone would import obsidian to the East Coast for fill. I've seen them use smaller tumbled quartz and quartzite gravel but no obsidian. That's a new one for me. They also use imported crushed granite, local limestone mixed with slag. I've found all sorts of odd material that has washed around from hurricane damaged buildings.
In the United States obsidian is not found east of the Mississippi River, as there is no geologically recent volcanic activity there. In the western US it is found at many locations in Arizona, California, Idaho, Nevada, New Mexico, Oregon, Washington, and Wyoming.
