One of my favorite websites on the internet is archive.org. It is a great research resource. Here are a couple of the links that relate to geysers. https://archive.org/details/texts?and[]=geyser https://archive.org/details/geysersofyellows00weediala https://archive.org/details/offtogeysersoryo00step There are plenty more texts out there but I'll let everyone explore the site on their own. If you go to texts and type Yellowstone there are also a large number of texts, well even more than geysers. Good luck and happy hunting :) Franklin Hessler -------------- next part -------------- An HTML attachment was scrubbed... URL: </geyser-list/attachments/20151103/700c9ffd/attachment.html>
