Old Faithful Visitor Center Logs
 

A log book of geyser activity is kept by park rangers and volunteers at the Old Faithful Visitor Center. The activity reported in this log mainly concerns the Upper, Midway and Lower Geyser Basins but other areas infrequently are included.

Lynn Stephens, Marion Powell and Mary Beth Schwarz have undertaken the monumental task of transcribing the handwritten log books onto the computer. Marion Powell and Mary Beth Schwarz have compiled the logs from 1970 to 1981. Lynn has compiled the logs from 1981 to present.

As common courtesy, if you use the data here, you should reference the log book as your source and include thanks to all of those that have contributed to it.
