The many waters
Ka wai kini is the multitude of waters — kini being a great number, formally forty thousand. The name belongs to a peak that stands in the same saturated summit region as Waiʻaleʻale.
At 5,243 feet Kawaikini is the highest point on Kauaʻi, about a hundred feet above Waiʻaleʻale, though Waiʻaleʻale is far better known.
Alakaʻi
Both peaks sit above the Alakaʻi, the high plateau bog that drains them. The rain that lands here is the source of most of Kauaʻi's fresh water.
