Columns of Steam & Water, Evening Geyser Lightshow, Yellowstone National Park, Wyoming

Mark thank you for your comment, like and question.

N/A, whether the shutter was released two weeks ago or half a century, what is the difference? Questions concerning with the when’s, and camera settings of a photograph in my humble opinion are missing the whole point of photography, being there.

Why thank you Juergen. You don't know how fortunate and thankful I am to this day to have been there to experience this event. Had it been for the geyser play/eruption this evening's sunset would have been fairly mundane and common place. A red ball sinking below the western horizon.
After peak lighting on some area mud pots ended. I wonder over to this geyser group and noticed some minor features bubbling and squirting. Not uncommon to see either of these but to see both at once could lead to bigger and better things to come. Throughout civil sunset one by one more and more of the geysers began to erupt as this thermal group began to glow due to the lowering sun due west. I began dashing here and there occasional changing lenses, franticly shooting not wanting to miss anything, yet not wanting to run out of film, causing a reload at an inopportune moment.
Glad to have had this experience, and able to share it with you and other members here @ fstopper, thanks for your interest and appreciation.
Have a Great Day!
Paul
