Conference on hydrology of volcanics in the western states UNITED STATES DEPARTMENT OF THE INTERIOR GEOLOGICAL SURVEY Water Resources Division Washington 25, D.C. In reply refer to: July 29, 1957 Code 4050 0001 GROUND WATER BRANCH MEMORANDUM NO. 58.3 To: District Chiefs and Staff Officials, GW Branch From: Chief, Ground Water Branch, Washington, D.C. Subject: Conference on hydrology of volcanics in the western states The attached tentative list of papers to be presented at the conference on Hydrology of Volcanics in the Western States and list of persons who have indicated they plan to attend the conference were compiled from responses to the Ground Water Branch Memorandum No. 57.38. The conference appears to have reached its optimum size; however, if for some reason there are one or two additional persons within the Branch who have been planning on attending, but who have not notified Mr. Mundorff, they should do so immediately. Likewise, if it becomes necessary for someone to drop out, Mr. Mundorff should be notified as soon as possible. Those who will require supplemental travel authorizations should submit them to this office for approval. As stated in Ground Water Branch Memo No. 57.38, if copies of papers to be presented are received in this office by August 5th, an attempt will be made to have them duplicated so that they can be distributed for review before they are presented orally at the meeting.
