The front half of the lava delta is shown, with an open lava stream left of center. In the upper left is a circular rubble feature, called a shatter ring, which formed between Aug 15 and Sept 19, and is the source of many of the lava flows on the left (west) side of the image. Yellow sulfur can be seen on some areas on the delta as well, especially on the right hand side of this image. Today the delta was measured at approximately 10 acres (4 hectares) in size.
