WELCOME

I grew up in Lancaster, Pennsylvania, then followed my mother’s advice to go somewhere “different” for college. In 1965, I moved to Boulder, Colorado. Now, more than five decades later, my roots are still in the East, but my heart –– and  my passion for researching and writing about history –– is in the West.
Colorado has remained my home.

Here, you will learn more about my books, current projects, articles –– and about me. Thanks for visiting my website.

In 1978, I started freelancing (followed by a history column) for the Boulder Daily Camera. My last Camera column was published on August 25, 2025. I now write for the Boulder Reporting Lab.

I’m also working on a new book –– Caribou, Colorado: The Allure, Lore & Remains of a Mining Town, about the (now ghost) town and its people, mines, and cemetery in Boulder County, Colorado. Former readers of cariboucemetery.com, are redirected here. Soon I will be updating the “Caribou Cemetery Project” under “Related Interests."

SOMEONE’S DAUGHTER 

Comments from "The West London Witch” (PODCAST ABOVE):
   Every now and then, a story grabs me and won’t let go.
   That’s what happened with the Boulder Jane Doe. After reading about the case and discovering Silvia Pettem’s powerful book, and her appearance in Web of Death, Jane Doe episode (Hulu documentary, 2023), I knew I had to speak with her.
   Silvia isn’t just a gifted author—she’s a masterful storyteller whose passion radiates both on the page and on screen.
   Her dedication to giving the Boulder Jane Doe her name back after 50 years of anonymity is nothing short of remarkable.
   Please enjoy this beautiful journey to give justice to Someone's Daughter.
