Today, I want to make sure that you're aware of some other great materials available through the USGS Multimedia Gallery. The USGS Multimedia Gallery contains large collections of educational videos, animations, podcasts, and image galleries. You can search each collection by topic, keyword tag, or year of creation. RSS feeds are available for each gallery. In addition to the videos in the USGS Multimedia Gallery you can find many videos on the official USGS YouTube channel.
