California Friday: Fireworks 2016!
Our next stop for California Friday is actually many locations. July 4th will be here soon and that means Fireworks! The fireworks app I have used for the past few years has been updated once again. This year I added Riverside County. If you love fireworks and want to find out where you can legally buy and shoot them off in SoCal, check out the app!
You can view cities in LA, Orange, Ventura, and Riverside County that allow the sale and discharge of fireworks. Included are days and times when fireworks will be sold and when you can light them up, as well as links to city web sites and telephone numbers. Data was collected from municipal codes, web sites, and/or contacting each city. Enjoy!
For a list of 296 communities permitting state-approved fireworks in California, check out the California Fireworks Newswire website.
A Modern-Day Mapmaker
Check out this article about Tom Harrison, a Californian cartographer who started his own mapmaking business in the 1970’s. His maps are made for hiking, backpacking, and mountain biking in the parks and wilderness of California. He explains what goes into a good map and why making one can take nearly two years.
You can order his maps from here.
New World Atlas of Artificial Sky Brightness
Check out this interactive map showing light pollution from urban centers around the world. Light pollution at night can blot out the stars, so the brighter the area, the harder it is to see stars in the night sky.
New Alquist-Priolo Earthquake Fault Zone Maps
The Alquist-Priolo Earthquake Fault Zone Act (1972) and the Seismic Hazards Mapping Act (1990) direct the State Geologist to delineate regulatory “Zones of Required Investigation” to reduce the threat to public health and safety and to minimize the loss of life and property posed by earthquake-triggered ground failures. Cities and counties affected by the zones must regulate certain development “projects” within them. These Acts also require seller of real property (and their agents) within a mapped hazard zone to disclose at the time of sale that the property lies within such a zone.
The California Geological Survey has released 7 new Alquist-Priolo Earthquake Fault Zone maps in the San Bernardino County and Tahoe Basin areas. Check it out.

Tribal Leaders Directory
The Bureau of Indian Affairs (BIA) first developed the Tribal Leaders Directory as an internal reference document for its employees. It quickly became one of Indian Affairs’ most requested documents, and is now used by federal, state and local governments, news media, businesses, researchers, and the general public as a resource to help them connect with Indian Country. The BIA’s commitment to enhanced communication led to transforming this publication into the electronic interactive map. Check it out.

Oblique Imagery of the West Coast
The National Geodetic Survey (NGS) deployed the NOAA Office of Marine and Aviation Operation’s King Air aircraft to complete the collection of geo-referenced oblique imagery of the West Coast. More than 3,000 images were collected from the U.S.-Mexico border to Cape Flattery, WA.
