In Utah, there are natural oil seeps at Rozel Point on the Great Salt Lake. The oil seeps at Rozel Point can be seen when the lake level drops below an elevation of approximately ; if the lake level is higher, the seeps are underwater. The seeps can be found by going to the Golden Spike historical site, and from there, following signs for the Spiral Jetty. Both fresh tar seeps and re-worked tar (tar caught by the waves and thrown up on the rocks) are visible at the site.
