I had heard about mysterious lake near the summit of Mauna Kea so I went there. There was snow in the shadow, though it was the middle of June.
There were two routs, down from upper place and up from the lower parking. Both are same distance, about 1mile. I thought it might be hard to clime when return, so I chose lower parking rout. But it was big mistake they were same distance but difference of latitude was three time higher than another rout and it was terrible hard to clime up at the beginning of walking because I did not use to thick air. I took over 1 hour.
There was a board like this. Old Hawaiians offered the umbilical cord (piko) of new born baby into the lake
to pray his health. Some one does now. It was thought as bottomless.
There are many volcanic bombs which we can see in the museum around there.
After the hard trial I found the lake but it looked like a puddle.
When I approach, it was small (1.5acre) but surely the lake (pond?) It is the highest lake in the USA at the 13020 feet high.
The question is why there is a permanent lake on such place. Lava rock cannot hold water, so there is few lake and hot spring in the Big-Island. Besides ratio of fine days are very high so many astronomical observatories gathered here. It means it cannot expect much rain.
How to keep this lake. Answer will be given next.
