Denver Calling: The Lost Book of Astrid Lee (vol 2) starts Friday, September 3 and runs through September 19. Groups—which can be any number of people, and large collaborations are welcomed—must register by Sunday, September 5 in order to participate. Registration ($10–30 per group) is now available with more information at

Participants in Denver Calling support local artists, musicians, and community partners while embarking on a self-guided, Covid-conscious, episodic mystery quest, solving puzzles in search of local history and new ideas hidden beneath their feet. It is organized by History Colorado’s Public Programs & Events Manager Chris Getzan and creative influencer Andrew Novick in collaboration with Barry Osborne of Denver’s Swallow Hill Music. The project draws on the talents and contributions of local musicians Distance Walk, Felix Fast4ward, Michelle Rocqet (Milk Blossoms), and Kalyn Heffernan (Wheelchair Sportscamp) to animate the quest in a way participants won't have ever seen—or heard!—before, along with original creations by Denver artists Lonnie Allen, Don Austin, Roxann Diffin, Emily Hope Dobkin, Cassandra Elaine, Thea Hunt, Cori Redford, and the students from Arts Street.

The quest runs September 3–19, with a multitude of sequential clues, each leading to the next pursuit (with “bonus offshoots” for the truly history-engrossed). Participants must start with the first week in order to complete the experience. "Think The Goonies meets Where In The World Is Carmen Sandiego with a dash of Twin Peaks, all right here in Denver," says Getzan. “This year’s quest is all about cooperation and coming together to unravel the past, and I guarantee you’ll learn something new whether you like it or not.”

Denver Calling is the latest element of the Building Denver initiative, History Colorado’s current slate of exhibitions, public programs, and partnerships that explore the growth, urban development, and architecture of Denver from 1860 to today. The initiative—which also kicked off its speaker series on August 12, and hosts the historical legal expert Dr. Tom Romero on September 9—supports Denverites to collectively envision a healthier, more inclusive, more equitable city. Dr. Romero will share a complex history of race and racism in “Colorful Colorado” and challenge participants to directly confront what racism means for people in Colorado today.

About Building Denver
Stoked by climate change, public-health crises, and a burning quest for more justice within our metropolis, Denver is in the midst of accelerating urban and social transformation. Its population has exploded over the last two decades, and while the city is more diverse than ever, it was also identified in a recent study to be one of the most rapidly gentrifying cities in the nation. How did we get to this point? Where are we, exactly? And where should we go from here? Building Denver’s critically acclaimed core exhibit, called Building Denver: Visions of the Capital City, and its many supporting facets help answer some of these questions.

Building Denver is made possible by generous support from Alec M. Garbini AIA, donors to the Executive Director's Innovation Fund, Bank of America, The City and County of Denver’s Community Planning and Development Department, Gates Family Foundation, Urban Land Conservancy, Continuum Partners--Mark Falcone, and RATIO/Dennis Humphries.
