Weather
In the Mauna Loa backcountry, be prepared for severe weather conditions any time of year, including blizzards, whiteouts, snow, and driving rain. Temperatures drop below freezing at night. The ahu (stone cairn) trail markers can be obscured by fog. Do not lose sight of the ahu behind you while looking for the ahu ahead, as it is easy to become disoriented. Sunlight is intense, especially with snow cover. Pace yourself as you ascend Mauna Loa, and be prepared for rigorous conditions. Altitude sickness is common there, so be ready for the necessity of moving back to lower elevations. For weather forecasts call 808-935-8555.
Volcano Hazards
Methane gas is created when lava flows over vegetation, filling underground lava tubes. When the methane ignites, the ground explodes up to 100 yards ahead of the advancing lava flow. Therefore, do not approach lava through vegetation! Another fascinating feature of volcanic activity that can also be deadly is benches. Lava creates new land when it enters the ocean. This new land is called a bench. The lava enters the ocean and solidifies into shattered pieces, which slide down the underwater slope. Rubble builds on the surface, giving the appearance of solid land. But the bench is unstable and can collapse without warning into the sea. Heed signs warning of closed bench areas.
