GSA Members & Friends,

Many of you know that GSA is headquartered in Boulder, Colorado, and that we are hosting our 125th Anniversary Meeting this year in Denver. You are probably also aware that unusually heavy rains have recently caused flooding of historic proportions in our area. Homes, property, and lives have been lost, for which we are deeply saddened.

While our GSA property is undamaged, and our staff is safe (if not completely unscathed) we are supporting our local Red Cross chapter in the disaster relief effort to restore our community back to its beautiful and prosperous state.

Please click here if you would like to make a contribution on behalf of The Geological Society of America. We thank you for your support, and we look forward to welcoming you in the Denver area very soon!
