GeyserTimes.org exists to collect and disseminate geyser eruption data.
Data collected on GeyserTimes.org are "open source" as licensed under the Open Source Database License (ODbL). The license allows you to share, create derivative works, and adapt the database, as long as you attribute, share-alike, and keep the data open.
Some of the most valuable geyser eruption data comes from Geyser Observation and Study Association (GOSA). The sources are the Old Faithful Visitor Center Logs as transcribed by Lynn Stephens and electronic monitor geyser data from Ralph Talyor. These data are identified on GeyserTimes.org by the observer name of "OFVCL-EV" and "RTED", respectively. Any use of this data should attribute the source as specified by GOSA on their website. Thank you to all that have contributed to the Old Faithful Visitor Center Log over the years!
GeyserTimes.org data and data-derived products, like prediction times, stem from user contributed data. Eruption data or predictions on this site could be highly inaccurate or erroneous.
