CDOT Completes Rock Bolting on Hwy 3 Near Durango

News Link
There have been 5 accidents caused by rockfall on this stretch of highway in the past 10 years. With an average of 8,700 vehicles per day on the highway and an average passenger load of 1.5, the incident rate is about 1 in 9 million, the same rate as the average for the whole state of Colorado. Maybe this mitigation work will knock the rate down a bit.

Video Summary of Boulder Floods of 2013

Video

This news report surfaced in my RSS feed for some reason. It is a good video documentation of the week-long flooding in the Boulder area and downstream. Some sensationalist stuff like saying it was a 1,000 year flood ( it was somewhere in the range of a 50 to 100 year flood) and the rescue of Roy Ortiz from his van submerged in raging flood waters. After his rescue, Ortiz sued the rescue team for not getting to him fast enough. After the suit was filed, Ortiz turns out to be an illegal immigrant!

Quietest 3 Year Period for Tornadoes in the US on Record

News Link
Every weather pattern goes through regular cycles of roughly 60 years, building up to an extreme maximum and then declining to an extreme minimum.  The records only go back through 1953 which means one cycle or less has been observed in detail with weather satellites.






Here's the graph of the number of tornadoes in Colorado vs the number of hurricanes in the US from an earlier post.  You can see that the number of tornadoes peaked in the 1990's and is currently declining toward a minimum.

Russian Scientist Discovers 1,200 Foot Asteroid

News Link
NASA has done a good job of identifying and tracking the largest near earth asteroids but so far only 11,000 of the more than 100,000 estimated near earth objects are identified and tracked. This 1,200 foot asteroid wouldn't be a world-ender if it struck earth but would completely destroy an area the size of Colorado.
