• "The Mapping of Colorado from Indigena to Statehood"

  • ​Tuesday, September 8, 2026 @ 5:30 PM MT, History Colorado, Downtown Denver

  • Author and map history enthusiast, P.J. Anderson, will discuss his recently published book, written to commemorate the 150th year of Colorado’s Statehood.
    Surviving maps trace Colorado’s pre-statehood history, showing what people knew—or thought they knew—from the 1400s to statehood nearly 400 years later. Ninety high-resolution maps depict expeditions, reservations, land grants, territories, surveys, trails, gold rush and mail routes, railroads, and city views. This publication also includes Colorado’s most complete cartobibliography, describing and discussing over 250 maps and where they can be found.
     

  • P.J. Anderson is a mostly retired attorney and former El Paso County Planning Director and County Administrator. He later practiced law in Colorado Springs, focusing on land use, municipal law, and special districts, and is a lifelong local history and map enthusiast.
     

  • You can purchase the book online through the author's website (please click here).
     

  • Note: This talk will be in person and over Zoom (link to be posted soon)

• ​New Feature in Colorado Magazine: “Lost and Found – Rediscovering Colorado’s Earliest Records” by RMMS member Larry Obermesik

  • ​We’re excited to share an engaging piece from Colorado magazine titled “Lost and Found: How my pandemic pastime led me to rediscover some of Colorado’s earliest records.” Over the course of the pandemic, RMMS member Larry Obermesik turned a quiet hobby into a remarkable journey through archives, unearthing forgotten maps, journals, and documents that shed new light on the early days of Colorado’s settlement.

  • You may remember that Larry presented the story to RMMS last year of Daniel Jenks, the early Colorado gold miner, from the journal Larry discovered in the Library of Congress. Larry has gone on to do amazing research on the Jenks family and uncovered important documents of broader importance to share with other researchers.
