However, much has happened since it went up, including the Blogger outage. Scroll down for a report on that.
However, there are a couple of spots on the island that are black sand beaches. The largest one is the beach at Waimea on the West Side of the island.
Waimea beach is a long stretch of beach. At one end lies the mouth of the Waimea River and the far end goes out past the pier and towards Kekaha.
It had been a few years since I had been to that beach and walked along the shore, and I have to admit that although it is not one of my favorite spots I found my trips there to be relaxing. There were also many things that I noticed about the beach, which I had never paid attention to before.
For one, there is a large stone by the entrance with a metal plaque informing visitors that the site is of historical importance because Captain Cook had landed there.
One of the first things I noticed when I stepped onto the beach is that the sand shimmers and sparkles. It is more of a dark brown color and the sand is very fine and gritty. The waves crash right on the shore and the beach slopes upward.
It is not a very wide beach, about fifty feet wide at the widest point and the beach slopes upward towards the backyards of the homes along the beach. Many of the trees that are growing on the boundaries of the beach homes have their roots exposed where the sand has eroded from the tides.
The color of the ocean is a brownish mixture probably from the sediments that wash down from the river and the dark sand of the coastline. About five hundred yards out beyond the pier the water changes to green, gray, and blue color.
The water is probably pretty deep and there does not appear to be any reef outside. That is probably the reason the waves only break at shore.
As I walked along the beach I saw many things like kukui nuts in all the various processes of aging. They varied from a light brown color all the way to a dark black; many of the black shells were cracked open.
There was a lot of driftwood, but no seaweed along the beach. Seedpods also litter the beach and there are numerous crab holes scattered along the coast. Along the shore break there are small to medium sized stones and pebbles. Many are worn smooth from the constant tumbling of the waves and sand.
Some of the pebbles are dark black, others are dark gray, and a few are reddish-brown in color. Many are smooth and not very porous, but there are also ones that are full of surface holes.
In one of those rocks I could see little bits of greenish-yellow glasslike minerals. There were also tiny glittering pieces that sparkled in the sunlight.Trip participants gathered at geology department, Makerere University and left at about after lunch using a taxi and then a public boardered a public bus to Kasese district.
