Celebrating 160 years of service to Missourians
One hundred sixty years is not a very long time when speaking in geologic terms. However, the Missouri Department of Natural Resources' Geological Survey is observing this noteworthy milestone this year. Since 1853, the Missouri Geological Survey has provided reliable scientific information to describe and understand Missouri's wealth of natural resources. Plan to visit us during our Open House, April 22-26. More info will be posted here about activities. Read the recent Missouri Resources Magazine article about the Missouri Geological Survey.
