To locate recreation maps in OneSearch, include .E63 in your search.
For example, a search for "Chuckanut .E63" will bring up a list of recreation maps of the Chuckanut Mountains and other locations that share their name.
Recreation maps are classified with Library of Congress call numbers. They are interfiled in the main collection and closed stacks in call number order by geographic area. Our set of GreenTrails maps is kept in the closed stacks area, but these maps are available to check out.
