Because it is relatively far from the boardwalk, at the center of a slightly raised dome, Arrowhead Spring
is difficult to view properly, its neat shape only visible close up, but of course off-trail hiking is not permitted. The spring has quite a small vent partly covered by semi-submerged sinter mats, and is usually full of water right up to the level of the surroundings, though on occasions it becomes partially drained. The name is due not to the shape but because an ancient arrowhead was once found in the pool.
