Cavers who disparage sea caves need to enter one by a sit-on-top kayak
following coastal shore with your climbing kit. Some lucky boaters find
an air chamber to float within at high tide where the only natural light is
an underwater glow out of your submerged entry. Others beach the hull
on wet slabs or cobble by swinging legs outboard to stand amid shallows.
All waves which arrive like engine pistons compress you wonderfully in
places you ordinarily do not fit. Most over-pressure blows by rushing
past rough entry ceiling. Such caves house life. Reader amid sea is no
longer an apex predator. Dead end caves become flotsam vaults. The
typical rubber compound laced fabric choices may float within even if
other portions are claimed by nature. It may be possible to exit cave
interior as wet compression often helps make upward vent. Writer has
climbed fissure and wider blow holes. Suggest jumar or prusik assist.
My last was a shale descent wearing MooseRacing ATV boots in August,
2012, nor were they suitable for climbing. Most of the planet population
resides near the sea. Suggest respect for coastal recreation resources.
