Since the Old Faithful Webcam is temporarily out of service, you can view these old postcards instead. Click on the postcards to view them larger. The above card is an unused Haynes postcard. The back reads:
Old Faithful Geyser, 150 Ft., Yellowstone Park, is not the highest geyser, but it is by far the favorite one. Its eruptions occuring every hour last about four minutes.

This unused “Phostint” card was published by Detroit Publishing Co.

This unused HHT Co. card reads:
In plain sight from Old Faithful Inn, and every 63 minutes without variation, winter and summer, day and night, gives its exhibition. Eruptions by moonlight, sunrise or sunset are most brilliant.

Here’s an article about those bears and their feeding grounds.
