As host of Chamorro. com, I've received literally hundreds of inquiries re our Mariana Islands, Chamorro culture and tradition, our language and on and on. The Pacific War is of particular interest.

I find Mr. Petty's book very interesting and believe it is a good place to start. What better way to know about the past, even if it is only the recent past and only a small part of the past, than to hear about it from those who were there and in their own words?

Basically, the sky atlas covers only the area from Polaris ('North Star') down to about Orion's Belt - everything south of there is contained in the 'Southern' book. Indeed, it doesn't even include the entire Orionus - cutting him off at the knees, in effect. So instead of obtaining sky maps that disclude everything south of Earth's equator (which 'uppers' normally would have little use for), this division discludes half the desired viewable sky!

The opposite is of course true for denizens of the lower-half of our dear blue vehicle.

The 'bottom line' is that to have an EFFECTIVE atlas, you're gonna have to spring for BOTH volumes - so be prepared for the extra expense.

One plus is the scale; larger even than the infamous Sky Atlas 2000.0 with its unwieldy poster-size maps of ~17×22" (add another 12" to the required footprint for an opened book; ergo 17 tall by 34" wide - a factor no one seems to consider) which pretty much relegates it (Sky Atlas) to an indoor reference, unless you have a sizeable reading table available at your viewing site!
But I digress....
The increased scale allows for finer detail, of course, and corresponds to the inclusion of stars down to magnitude 9.5 (Star Atlas limits to 8.5) with a better 'spread' for comparison to telescopic view. This greater scale with smaller pages does translate to more charts (about 260 in this one volume, ~vs~ Sky Chart's 26), but this is no complaint - the detail IS appreciated by the more studious ..of us astro-freaks. Another nicety is the generous overlap of the borders, which minimize somewhat the necessity of having to go to another page when referencing a particular area. Probably one of the 'handiest' features is inclusion in the margins of index-reference numbers to adjoining charts (sorely lacking in the Sky Atlas), which makes up somewhat for that maddening right-left reversal of borders on adjoining opened pages - the necessity of which absolutely escapes me, but for which I've seen hints of correction in the soon-forthcoming new issue.

Another plus is the textual introduction and Uranography sections preceeding the charts. Do yourself a favor and read them first - it might help you avoid the extra expense of the 'Field Guide' to better understand the valuable resource you already hold.

But as said - you need both Northern & Southern volumes to have an effective tool. So heads up!

The two volumes include 473 charts, making finding the right one a bit of a chore - the flip side of a large scale. For some reason Tirion chose to arrange the charts in a weird way. Right ascension on a chart increases from right to left (naturally), but RA from one chart to the next increases left to right - so the left edge of the left hand page matches with the right edge of the right hand page. It took me a long time to get used to that.

My two volumes have been marked with comets and asteroids I've observed along the way, as well as observing notes on the deep-sky objects, so I don't know if I'll care to replace them with the new edition, even though (as I understand) the new charts, based of the Tycho and Hipparcos catalogs will be far more accurate. But for a new observer who plans to be halfway serious, and can't quite spring for the Millenium Sky Atlas, the new edition of Uranometria will be indispensible.

BUY IT and ENJOY!!!!!!!!

Michael Malone, a historian at Montana State in Bozeman, must have felt the same way. He did some good, scholarly research, and found out that many of the wild tales WERE true!

The book is VERY readable, almost like a novel, filled with some wild stories about how the three "Copper Kings" (Butte's version of "Robber Barons") worked, wheeled, dealed, cheated, competed and conspired to make as much money as they could from "the richest hill on earth."

In the mix are many stories about the everyday Butte residents, who, to this day, are actually friendly, big-hearted people...who put their hearts and backs into the building of the town.

Butte, Montana truly is "as ugly as sin" (quickly verified by any who has been there), "and just as fascinating."

In 1975, the original "Roadside Geology of Northern California," with the same authors, presented a new way for the amateur rock enthusiast to learn about the complicated geology of northern California. Unfortunately, it was painfully vague, missing important information found in other books of the series, such as significant insight into how formations developed and their ages (e.g., Cretaceous, Devonian, etc.). By in large, this Y2K update solves the problem, and expands the original's spatial coverage southward to San Luis Obispo and the San Joaquin Valley. The improvement in information is phenomenal -- partly because of the increased knowledge gained in 25 years as alluded in the preface, but mostly because of better writing and attention to detail. For example, the Chapter 4 (Coast Range) discussion on how different rock types develop from different areas of ocean sediments may be the best I have ever seen in any forum -- concise (4 pages) and non-technical, yet stuffed with information. Like several other areas of the book, it includes interesting insight into how geologists have handled the difficulties in classifying and sorting California's wild assemblage of rocks; for example: "During the late 1960s, geologists finally accepted that large parts of the Franciscan complex are almost hopelessly scrambled. They agreed to call these chaotic jumbles melanges....Recognition of melanges was, in a way, an admission of defeat." Other chapters contain similar nuggets of "inside" information into the processes of rocks and the way they are studied.

Of course, the foundation of this book, as in the whole series, is in its sequential descriptions and explanations of the rocks one encouters while driving various roadways. The improvement in detail here is vast as well. There are still a few ambiguities in rock age (e.g., Paleozoic/Mesozoic schists of the northern Klamath region...aren't the actual ages more precisely known?). A few typos or fragmented sentences appear to have escaped the proofreaders. But overall, this is a well-composed and thorough look at northern and central California geology for the layman. Residents and vacationers who want to know about the rocks they see must have this book. It has greatly helped me to understand the processes behind rocks I have gathered there.

The book provides a plethora of information for those who wish to see the many interesting and complex geological features of the northern and central areas of California. However, in order to make the best use of this book and fully appreciate the physical and historical geology presented, the reader should have a basic background in geology. This book will even refresh the memories of those folks with a somewhat oxidized recollection of rocks, minerals, geologic structures, and the like.

This book is not aimed at rock hounds, as its emphasis is not on collecting. The educated collector will find it interesting, though.

There are only two "problems" with this book. First, it will lengthen the trips you take as you look for the geologic features it discusses. Second, you may endanger your life as you stop to look at the road cuts discussed in the book or divert your gaze from the road to rocks while driving.
