Field Stop 12: Halemaumau Crater
Field Stop 14:
Ocean Entry @ Holei Sea Arch
FIELD STOP 14: OCEAN ENTRY @ HOLEI SEA ARCH
After our rainy morning activities we headed further down Kilauea on Chain of Craters Road to the point where past lava flows have covered the road. Near this point is the Holei Sea Arch and a park ranger station of sorts where tourists can buy water and snacks and talk to a H.V.N.P. ranger. This stop consisted of looking at the Holei Sea Arch, eating lunch and (hopefully) finishing drying out to get ready for our lava hike. Refer to Site Map for location.
Fig. 1: View of Holei Sea Arch facing south. The cliff is about 90 feet tall. The area closest to sea level erodes faster
and is undercut by the waves, which eventually causes collapse. Sea arches, like Holei,
are formed due to variation in wave patterns and in lava hardness. In order for the arch to persist it
must be more dense and resistant than surrounding material.
Fig. 2: View of the coast looking northeast from the sea arch. Note the black sand eroded
from the basalt. Red arrow marks steam cloud where lava is currently flowing into the ocean.
