SUCCESS Meetings

SUCCESS Science Meeting 24-26 October 1996

NCAR Boulder Co.


All meeting sessions, except for Thursday afternoon (after the lunch break), will be held at the NCAR FOOTHILLS LAB (not to be confused with the original Mesa Lab, which is the I.M.Pei building up on Table Mesa, "the Big Pink"). The Foothills Lab is a group of three buildings located at 3450 Mitchell Lane in northeast Boulder. The meetings will be held in the main conference room in the center building. On THURSDAY AFTERNOON the sessions will be held at the MESA LAB at 1850 Table Mesa Drive in southwest Boulder. The meetings here will be conducted in the main conference room on the mezzanine. There will be a cash bar at the Mesa Lab site immediately following the sessions on Thursday afternoon.

We have included a street map on the web page for locating both NCAR sites as well as the hotels.

NCAR has a web site for getting more info, which also contains a link for Boulder that has all kinds of info for getting out and about around town. NCAR Site:

There is also a nice University of Colorado site with helpful descriptions of getting to and around Boulder. CU Site:
