-14- <br />Mine property. If this were indeed the case then there is definitely <br />just grounds for further investigations to determine the flora and its <br />paieoecological significance. This new investigation should be conducted <br />by a paleobotanist during the removal of the overburden to expose the <br />coal seams. Part of the study should take place with several undisturbed <br />sections to formulate some type of stratigraphic control. Another part <br />of the study can be carried on with little interference with mining <br />activities as this would take place in the waste rock piles and would <br />involve searching for specimens. It will be necessary to maintain some <br />type of stratigraphic control throughout the thirty year life of the <br />mine as it is possible that [here were subtle changes in the flora during <br />the Cretaceous. Because of the immence volume of rock that will be <br />removed yearly examinations should be made to insure that specimens not <br />be lost nor that there is a loss in stratigraphic control. There is an <br />enormous wealth of data available for study in the Colowyo Mine [hat <br />would have gone by unnoticed if this study had not taken place and it <br />shows the need for similar investigations for all Federal lands to be <br />sure that no data of the past be lost. <br /> <br />• <br />l J <br />
