We gather members annual for conventions featuring presentations & outstanding photography concerning a wide variety of Rio Grande subjects.

The Society's Board of Trustee is pleased to announce that our convention committee is in the primarily steps of planning our return to an in-person RGM&HS convention event in August 2023 in Denver Colorado.
