Diane Brownlee will be leading us on a bus tour to see how water changes the landscape. Rivers of all sizes have been major factors in the landforms of the Blackland Prairie and how the early geology of this area can be seen in the creek banks and rivers and road cuts. We will begin in McKinney at the Heard Museum, visit the Richardson Environmental Center site and move east to the Sulphur River. Fossils will be seen in many of the areas. Leave promptly on Saturday morning at 8:30 and return by 4:30. Take a lunch. The cost of the bus is $25. Water and snacks will be provided. Contact Sally Evans at 972 248 6283 orsvevans@sbcglobal.net
