David Schwaz is correct and Kitt was very close. The first picture is East Vent. This was from the same amateur photo album as the Giant picture I posted last week. The cover of the album is inscribed "Remembrances on our trip through Yellowstone Park from Louis de Crignis to Mr. and Mrs. J. E. Dean, Aug. 5th to 12th 1907". I've attached one more geyser photo, this time showing both Fan and Mortar. Between the three (Sunday's, Monday's and today's) you can pretty well piece together what the formation looked like at that time. I found it interesting to note how much the formation has eroded in the last 100 years. East and main vents have both changed significantly. As Tara pointed out, main vent had a cone and as for east vent, well the lack of erosion is what made it so hard to identify. Near the center of this picture, it is also possible to see part of the old road bridge that once crossed the river just down stream from Riverside. For fun, I've included two additional pictures documenting the tourists' camp. Dave -------------- next part -------------- A non-text attachment was scrubbed...
