| Beautiful fractured Atoka Sandstone at Natural Dam. How would seismic waves behave in such a material? Can we do direct seismic experiments to measure anisotropy in situ? Probably, if we can find a company to sponsor the research. |

| Natural Dam is also a fine place to swim or have a quiet lunch |

| Site is about 50 mi SSW of Fayetteville, on the north hinge line of the Arkoma Basin. |
