In interior Alaska, the deadly poisonous "western water hemlock" is usually confined
to hot springs.   The species is found at Circle Hot Springs.  The "northern water
hemlock", Cicuta virosa is much more common in our area, being found adjacent to
the many thaw lakes scattered throughout the region.
