Under whose omophorion do they fall?
Stuart,
Idaho is within the geographic jurisdction of the Eparchy of the Holy Protection, but the monastery wasn't listed in the 2008 Official Catholic Directory, the most recent edition that I have, nor is it listed on the eparchial website. (I also checked St Nicholas in Chicago, to see if it was actually UGCC, but found no listing there either.)
It's hosted on the site of the local Dominican Third Order.
I recently received limited info on it in regard to the directory (nothing more than the info on the website). Its canonical jurisdiction was not cited and the means used for contact didn't afford an e-mail address for follow-up.
My guess, it may well be a fledgling looking for a nest (not the first). If anyone knows Father Irenaeus, indicated to be the acting superior, it would give a clue.
Many years,
Neil
