Preparation of these materials has not been a commercial endeavour. Rather, it is my way of sharing knowledge and encouraging you to enjoy the geological delights of Skye and Raasay.

I sincerely request that, if you choose to download and use these materials, you make an appropriate donation to the charity Disasters Emergency Committee through their website Based on the current prices of shorter and more restricted geological texts/guidebooks, only available in traditional printed format, I suggest a figure of £20 is appropriate, although more will be appreciated. Remember, it is better to give than to receive: with your help, we can make a difference.

Individual photographs in the Gallery, many of which are high resolution JPEG images, are available without the © Brian Bell watermark on request, in return for a charity donation (see above).
