Hoeman, Vincent D. 1964 21 We drove up to the pass again and waited while it got dark. Then at 1910 hours I heard them come in - the first calls from the direction of the cinder cone. Larry didn't believe me at first, they were so faint he thought it was his stomach gurgling. But the eerie "Cooah-Coah- Cooah" became louder with some ptarmigan-like clucking on the end so we knew and rushed out and up the cone, but they weren't landing just circling the puu in apparent courtship flight, a pair with high and low voices and occasionally a third bird, though a fourth may also have occasionally been in the are. They seemed to come a little closer when we first imitated them and we saw their white bellies in our flashlights' beams, but they were more interested in their own gyrations. For two hours we enjoyed their music then went back south, I climbing 9096 feet up Puu Kaiwiwi on the way. We spied on animal I think was a mouflon sheep briefly as it crossed the road. Temperature at 2200 40o F. We drove up the new Mauna Kea Road to its present end at about 13,300 where the 2300 temperature was 31o F. I wanted to go on up but Larry didn't want to wait. So we went all the way out to the little road opposite Kuimana cave to sleep in jeep because of the rain. April 28--Gas up in town and wait around for post office to open to check for Huber's binoculars. Finally get started for Mauna Loa. I'd visited the weather station guy at the airport yesterday and he said there were no locked gates so we took the road off the Saddle Road just before the Puu Huluhulu but took two right turns that were wrong before we got on the long swith back of the weather station road which would have been passable by "Impala" to the 11,150' weather station whose big argon light we've been seeing
