At Yellowstone National Park, Old Faithful had us betting on how close to the predicted time it would erupt (it was almost a half hour off)
I started this sketch before the eruption, accounting for capturing the eruption while it happened.
Below is the finished sketch, completed as the geyser went off (Photo taken when it was all done).
While it’s always exciting to watch a geyser that you know will go off, it’s especially exciting when you sit by a unpredictable geyser and are the only person by it when it suddenly goes off and puts on quite a show. No warning or tell-tale pre-going-off signs for Castle Rock Geyser. It put up a show for a few minutes.
That’s a sketching experience I’m not going to forget soon!

Thank you for posting these lovely sketches. It makes me “homesick” for a place I worked for 10 summers. I was just starting to sketch and was always unsure how to tackle the geysers so consequently I don’t have hardly any sketches. Thank you for sharing!

wow, that must have been an incredible experience. One day I’d love to do an extended stay, drawing in the park…
