I paid another visit to the grove of cottonwood trees near Mary’s Lake at the Rocky Mountain National Arsenal. My last visit, two weeks ago, showed the vibrant colors of yellow-gold of the leaves. Since then we have had snow and wind, so I expected to see some barren trees. The leaves of the cottonwood are shiny and triangular with rounded teeth on the margin. The nearly heart-shaped leaves are similar to poplar and aspen, also members of the Poplar family. We are moving on to winter and then I will try and get a photo of them in a blanket of white.
