The Gar Creek mudslide on the morning of July 12 had me, at the time, trying to accurately place the disaster on Google Earth. Unlike bimmjim, one of the commenters to the Yahoo! retelling of that news, I knew that Johnsons Landing was (obviously) slightly north of where Google Earth spotted the location. David Petley (who writes a landslide blog) had the correct map placement, verifiable by this helpful graphic.
The Fairmont Hot Springs mudslide on July 15 had some in the media trying to relate this event to the Gar Creek one by proximity. The National Post headlined it as 45 km away. I had already measured the distance as ~78 km (as the crow flies) and decided to let the Post know of its error. Incredibly, this evening's CBC - The National suggested that the distance between the locations was only 30 km (at 4:50 into the broadcast), which had me remeasure the damn thing in case I had made some dumb mistake. A little later, I chanced upon Brad Giffen (a CTV news-channel anchor) using the 45 km figure. What is this contagion?
Update: At least one subsequent story got it right.
