- Currently, a 2019 photorecord from the vehicle turnout at the top of the spillway of Terrace Reservoir in Conejos Co, and a 2020 iNaturalist photorecord (#55427446) from Alder Creek subdivision near South Fork in Rio Grande Co may be the only two documented Ratibida columnifera from the Watershed. Ackerfield (2022) also shows Coneos Co, with no voucher in SEINet. The species is fairly common in the San Juan River drainage of Colorado, with the closest occurrence to the Watershed being the Wolf Creek overlook (on Hwy 160, west of the Continental Divide). Often the flower seems to have been dispersed by human vehicles. In the USA, Mexican hat is largely a flower of the Great Plains and the Rocky Mountains, as well as northeast Arizona and southern Utah. It is solidly present in the Rio Grande drainage from the counties of New Mexico that border Colorado all the way down to the Gulf of Mexico.
