I live in the UK but my work, for a gravity gradient survey company (mineral exploration), takes me to some beautiful places. My job mainly involves low-level flying so many of my photos are from the air but close enough to the ground to see some detail. Geo-locating should get easier now that I've finally bought a hand-held GPS receiver!

Wow! Nice contrast between the sky/water and the lights.

The old road was so badly built that they decided it wasn't worth repairing - they just laid a new one alongside. The Trans-Kalahari Highway forms part of the road between Durban and Walvis Bay used by huge Namibian trucks but also donkey traps and ostriches.

The Jwaneng Mine Aquarium is the tallest building in Botswana, named because it houses a CARP (completely automated recovery plant) and a FISH (fully integrated sort house).

Ancient seabed under the desert. Millions of years ago diamonds, washed from eroding kimberlites far inland, travelled by river to the coast where they ended up in cracks and holes before the expanding desert covered everything. Now workers wearing big gloves (so they can't pick anything up) pick at the rock and suck the material into yellow mobile safes to be taken away for sorting. The diamonds are all gem quality and, being from various origins, can have a variety of colours.

The Irish Midlands are scarred by peat removal to feed power stations. It's a valuable resource especially during times of high oil prices but it's making a horrible mess of the landscape.

I was told that these marks are old scars (perhaps 100 years old) caused by termites working over the soil around their colony

Jwaneng kimberlite yields about 1.3 carats of diamonds per ton of rock. The high proportion of gem-quality diamonds makes it the richest diamond mine in the World. The ore contains other minerals such as garnets, visible here, but they are not recovered.

The green rock is kimberlite, the diamond-bearing volcanic pipe intruded in the redder country rock

These terraces (often there are several rows) should calm the water and allow suspended particles to settle out. This will reduce turbidity and promote aquatic vegetation growth. The sediment build-up on the terraces will provide a habitat for fish, shrimps etc.
