Both in 2020 and 2021 the brother next to me and I backpacked in the Rocky Mountains west of Aspen, Colorado. Last year we did part of the Four Passes Loop in the Maroon Bells. This year we hiked to Cathedral Lake and Electric Pass and this year we each took a grandson along. Neither trip was for the purpose of seeing native orchids but we did see a few, all of them familiar to me from the Pacific Northwest.
Platanthera dilatata var dilatata (Tall White Northern Bog Orchid)
Platanthera huronensis (Green Bog Orchis)
Platanthera x estesii (Estes Hybrid Rein Orchis)
Goodyera oblongifolia (Giant Rattlesnake Orchis)
