The Colorado Scientific Society usually has Spring and Fall field trips. Here are trip guides, maps and pictures from past field trips. The most recent field trips are listed first.
The field trip guides for some field trip’s can be downloaded, usually as PDFs. The size of files larger than 3 MB is called out in the link, e.g. “Quaternary San Luis Basin, Ancient Lake Alamosa, 2007 (PDF 4.6 MB)”. In most documents, of the text is
Field trips are grouped by decade, with the most recent first. Some field trips with many pictures and maps have their own pages.

Information about Field Trips
- Field trips include links to digital copies (PDFs) of trip guides and maps. Clicking on a link will open the PDF in a new tab.
- The text in the linked articles looks original, but it is searchable and selectable. (Text in maps and cross-sections in NOT searchable or selectable, because this can degrade the figure.)
- The sizes of large downloadable files maps are listed in the name.
