A screenshot from Geosites showing information related to one of the geological sites on the website. In this case, it's of Glasgow's Necropolis and shows a map, a summary of the site and photos, as well as links to other resources such as walking guides.

Colorado: Our best bet to see the storm will be just after sunset tonight. Look north around ~5:30-5:45p. Fingers crossed this holds until sunset tonight!

Solar storm is ongoing - fingers crossed this holds until sunset! If so, should be a great show.

These trees look like Jimmy Hendrix & Claude Monet did a collab, but this is just what the rainbow eucalyptus (Eucalyptus deglupta) looks like every day: fabulous.
