Detailed Description

Lava spines continue to emerge onto the crater floor of Mount St. Helens in 2005. By April 2005, spine 4 is broken and pushed away by spine 5.  The nearly vertical spine 5 has a smooth, gouge-covered surface, growing at an average rate of 4.3 meters per day. Scientists continue helicopter overflights to measure the temperature of the lava dome and assess hazards from dome collapse.
