1. MAWY and OFWY sites are linked via telephone links to an internet connection using a UU PC computer running ftp protocols at NPS Yellowstone NP headquarters, Mammoth, Wyo.

2. WLWY and HVWY are linked via spread spectrum radio links to the Mt. Washburn repeater, then via local phone lines to an internet connection using a UU PC computer running ftp protocols at NPS headquarters, Mammoth, Wyo.

3. BBID will be telemetry via a spread spectrum link to the internet via a UU PC at Rexburg, Idaho.

4. TSWY is linked via a spread spectrum radio to the internet via a UU PC at the Teton Science School at Kelly, Wyoming.

5. BIL1 is a CORS site near Billings, MT, that we acquire daily data from for our routine processing.
