Los Amigos de Valles Caldera News:

Los Amigos de Valles Caldera Board Member Billy Smith saw the article “What the Trees Tell Us” by Elizabeth Miller in the Spring 2026 National Parks Conservation Association Spring Newsletter.

This article discusses the dendroglyphs that exist on the aspen trees on Valles Caldera National Preserve.

Los Amigos would like to pass along the link to this informative article about the sheepherders who carved the dendroglyphs and work by volunteers and NPS staff to document their locations: https://www.npca.org/articles/11349-what-the-trees-tell-us
