About the HAO Exhibit

To celebrate the High Altitude Observatory's 75th anniversary, the NCAR Archives is pleased to present the HAO Online Exhibit. The Archives holds a large collection of historical HAO records, including Walter Orr Roberts' handwritten logbooks, early newsletters and reports from the Climax Observatory, and hundreds of photographs. Some of these materials are highlighted in this exhibit and many more are available online. Please contact us with further questions, reference inquires, or possible donations to the collection.
