I don't know if this will be a help or not, but attached is a photo that shows Round Spring in eruption on May 25, 1990. Note that this is Round Spring itself. The slight bit of steam visible at the far right edge of the photo is from Round Spring Geyser and/or its adjacent UNNG-RSG-2. At the back left of the photo a portion of the pool of Pear Spring is visible; Pear Geyser (not visible in the photo) lies at the right end of the pool.

Episodes of frequent eruptions (intervals <20 minutes) were separated by an undetermined number of hours of quiet. A pool nearby was full and overflowing during Pear's series of eruptions and often not full at other times. That's probably the feature listed as "Pear Spring" in T. Scott Bryan's book (3rd edition). -------------- next part -------------- An HTML attachment was scrubbed...
