This lava tunnel is called Mary's Trumpet. Not sure what Mary we are referring to here but it is a trumpet because of the shape of the tunnel. When the water rushes in, it fills the space in the back so that when it comes back out there is a bit of noise.
Here, on the southern end of the island, we are under the eaves of Haleakala and its frequent cloud cover. Looking up the hill in the general direction of the volcano, we see a variety of cinder cones.
On the last day in Maui, we drove south to La Perouse Bay to see what we could see. The beach here is very rocky, covered with lava. Amongst the lava outcroppings are these small yellow butterflies.
