Vog Plume wraps around Mauna Loa

During a drive from Hilo down to South Point I went through the plume of vog coming from Halemaumau crater. Just past the Mauna Loa Road I entered the plume and was in it for about 11 miles. Going downhill towards Pahala I saw the plume stay above 2,000′ elevation and wrap around Mauna Loa. When I got down to South Point I could see the vog clearly wrapping around Mauna Loa and heading NW to Kona. It looked pretty bad towards Kona. South Point was clear and windy, as usual. The forests must be taking gas from all the vog.
