Reasonable suspicion is defined by a set of factual circumstances that would lead a reasonable police officer to believe criminal activity is occurring. This is different from the probable cause (what a reasonable person would believe) required for an arrest, search, and seizure.
Black Sand Beaches. Black sand at Kalapana. This new black sand beach is forming after the old one was swept away by a lava flow in 1986. The sand on all black sand beaches on Hawaii is made out of tiny fragments of lava. In contrast to the green and white sand, most of the black sand is created almost instantaneously. When hot lava enters the water it cools down so suddenly that it solidifies, and shatters into large amounts of black sand.

Return to Maui Beaches or Road to Hana from Maui Black Sand Beach. The park has facilities that are in short supply along the Hana highway-restrooms, showers, trash cans, drinking water, camping and cabins. You even get a great Hana coast view of Pailoa Bay as soon as you get out of your car in the large parking area.
