|Thanks for your nice comments. I found this orchid beside the road too but at a higher elevation.
I know what you mean about the darker sepals, I found more burgundy coloured sepals in my books but did also see the lighter ones. There is another white orchid similar to this one but it's only found in Manitoba and Ontario.
Waterton is an amazing place, full of unique flowers and amazing wildlife.
