He has worked on survey and excavation projects for numerous cultural resource management firms and the National Park Service's Western Archaeological and Conservation Center.

Park Ranger Allen Malmquist feels that he has an historian’s dream job.  As the historic structures repair specialist at the Lees Ferry and Lonely Dell Ranch National Historic District he researches the history, recommends repair and rehabilitation, facilitates consultation with agencies concerned, and then actually gets to do the repairs himself.

“There is great satisfaction in seeing one of these special buildings repaired and open to the public.”   He also maintains the orchard and historic garden and shares the history with visitors.

Allen studied geology and history at Stanford University, traveled extensively throughout the Southwest, and spent three seasons as a historian at Pipe Spring National Monument.  He earned an education degree from the University of Arizona and taught school in Page for twenty two years.  He is best known in the Page community for the outrageous field-trip/back-pack geology classes he taught for Yavapai College throughout the 1980s. 

He worked summers as a seasonal interpreter at Glen Canyon NRA in the late 1990s.  After retiring from the school in 2000 he has dedicated his “retirement” to preserving the history of Lees Ferry.
