Aerial counts, in-person interviews, and mail-in questionnaires were used to survey sport fish use during the coho salmon (Oncorhynchus kisutch Walbaum) season on the Copper River Delta, Alaska from 2002 through 2006. Angler counts provided an index of use on individual streams and were used to develop a spatial database exhibiting patterns of use. In-person interviews and mail-in questionnaires were used to determine the effort, catch, and harvest of coho salmon by both local residents of Cordova and nonresident anglers.

Why Copper May Become Your Favorite Metal

[jump to video]

Long story (not very) short? One night in 2003--after killing it in front of audience of about 30 lucky people in Oakland--The Long Winters needed a place to crash, and my wife and I were happy to oblige. 

So, they drove their Big Stinky Blue Van over the bridge, slept on our floor, and by breakfast the next morning, it'd become clear to me that I'd provided lodging to a man who was not only very likely a member of my karass--he was also one of the smartest bullshit artists I'd ever met. 

Almost eight years later, although I don't see him nearly as much as I'd like, I still count the guy as one of my best pals ever.

That's John Roderick. And, I think you need to know about him.

John doesn't read this site--he's more of a Twitter person--so I don't risk feeding his astounding excess of dignity by saying he's one of the most gifted writers and bon vivants of our generation. He's just the best. In large part because he's congenitally incapable of suffering bullshit.

This was never more apparent than the Saturday morning in 2007 when we sat in my back yard and talked about a lot of stuff. Playing guitar, advertising on the web, the evil work of promoters, and why everyone is always trying to shortchange everyone on copper pipe. 

That talking became a four-part interview I ran on the late and occasionally lamented The Merlin Show, and, to this day, it's one of my favorite things I've been lucky enough to post to the web.

So, y'know how I'm definitely "not for everyone?" Well, John is really "not for everyone."

He's opinionated and arrogant and undiplomatic and unironically loves Judas Priest--meaning everyone will find at least one thing not to like about him. Despite being hairy and enjoying laying on your bed, John is not exactly a teddy bear. 

But, John's also right a lot. And, he never sands off the edges of his personality or opinions to make you theoretically "like" him. Which, it will come as no surprise to you, is a big reason I love the guy more than a free prime rib dinner. 

So, why the jizzfest about that awful jerk, John Roderick?

Because, as I noted the other day on the Twitter, in our first episode of Back to Work I misattributed a line that should have been credited to John. Which in itself is unimportant, except inasmuch as finding that link to correct the error got me watching our 50-some minutes of chatting again. I also received some at-responses and emails that reminded me how much people enjoyed our chat. 

But, really it made me realize how much that rambling morning in my back yard still resonates so much with stuff I care a lot about. Independence. Agency. Directness. And, never apologizing for wanting to get paid. Also, guitars and talkative hippies.

So, anyway. John. 

I edited all four parts of the video into one big (streamable/downloadable) movie that should make it way easier to watch at a sitting. Should that interest you. Which it may not. Which, as ever, is totally fine, and kind of the point.

But. If you like Dan and my new show (and, seriously—God bless you magnificent bastards who helped briefly make B2W the most popular podcast in the world [gulp]), I think you'll really like this interview a lot too. I hope so, anyway.

Thus, submitted for your disapproval, permit me to present my four-year-old visit with the acerbic, opinionated, and reportedly unlikeable bullshit artist whom I respect and adore more than just about anybody. 

Meet Hotrod.

This is the thrilling account of an extraordinary life in law enforcement. Specialising in technical surveillance, Victoria Police Inspector Andrew Atkinson dedicated himself to ridding our world of murderers, corruption, terrorists and underworld crime syndicates. Now retired, Atkinson can let us inside his days as a peacekeeper in East Timor with the United Nations, an advisor to the Australia-New Zealand Counter-Terrorism Committee and the deceptive world of police surveillance.

Twenty wildland firefighters from Delaware are battling the Copper Mountain Fire, a 180-acre blaze located four miles east of Eastport, Idaho on the Canadian border that is 20% contained as of August 12. Delaware's crew comprises part of  the 137 personnel currently assigned to the incident.  Michael A. Valenti of Dover, Delaware's state forester and crew boss for the team, reports that firefighters are working in rough terrain and completing very long hikes to and from the fire each day.

In the past decade, significant research efforts have been devoted to mineral chemistry studies to assist porphyry exploration. These activities can be divided into two major fields of research: (1) porphyry indicator minerals (PIMs), which are used to identify the presence of, or potential for, porphyry-style mineralization based on the chemistry of magmatic minerals such as zircon, plagioclase and apatite, or resistate hydrothermal minerals such as magnetite; and (2) porphyry vectoring and fertility tools (PVFTs), which use the chemical compositions of hydrothermal minerals such as epidote, chlorite and alunite to predict the likely direction and distance to mineralized centres, and the potential metal endowment of a mineral district. This new generation of exploration tools has been enabled by advances in and increased access to laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS), short-wave length infrared (SWIR), visible near-infrared (VNIR) and hyperspectral technologies. PIMs and PVFTs show considerable promise for exploration and are starting to be applied to the diversity of environments that host porphyry and epithermal deposits globally. Industry has consistently supported development of these tools, and in the case of PVFTs encouraged by several successful blind tests where deposit centres have successfully been predicted from distal propylitic settings. Industry adoption is steadily increasing but is restrained by a lack of the necessary analytical equipment and expertise in commercial laboratories, and also by the ongoing reliance on well-established geochemical exploration techniques (e.g. sediment, soil and rock chip sampling) that have aided the discovery of near-surface resources over many decades, but are now proving less effective in the search for deeply buried mineral resources and for those concealed under cover.
