Pequonnock Valley History

I have had a fascination for this park ever since I started mountain biking there ages ago with my son. Old abandoned mills, a rail trail full of history and magnificent scenery make every visit an enticing adventure.

Researching history thru old maps always brings little rewards of discovery. A remnant of an old path semi-obscured in the woods... the mystery behind an old foundation... discovering and learning their origins keeps me coming back for more :-)

Great Flats Aquifer

The Schenectady Aquifer (a.k.a. the Great Flats Aquifer) is one of the most productive aquifers in New York State. It is also and he most heavily pumped aquifer in upstate New York.

Schenectady first tapped the aquifer as a water source in 1897. Today, Scotia, Glenville, Rotterdam and Niskayuna also draw their main water supplies from the aquifer, a total of 24 million gallons per day. The Department of Health estimates as much as 65 million gallons could be safely withdrawn.

The Great Flats Aquifer is a large deposit of water-saturated sand and gravel that was deposited as glaciers receded around 10,000 years ago. A large lake some researchers have compared to Lake Ontario drained into those sands.

Very Cool Interactive Map Exhibit

Mapping the Territory: Hudson County in Maps, 1840-2013

This exhibit featured maps of all varieties: topographical, infrastructure, transportation, sea level and birds-eye views. These maps showed how the region evolved geographically from forests, marshes and towering granite cliffs populated by Native Americans; to farms, settlements and villages built and inhabited by the Dutch, followed by the British and the newly independent Americans; and ultimately into the diverse, vibrant communities we live in today.

Graphing Jazz

Is Jazz Dead?

Even though Miles Davis’ 1959 Columbia recording “Kind of Blue” is still the biggest selling jazz album of all time with more than 20 million sold to date— Sony’s Columbia label, the former home of Miles Davis’ recordings, no longer signs jazz .

“With the advent of the celebrity-as-musician trend in the 21st century, artistry is quickly going by the wayside. Many of today’s popular artists can’t sing or play an instrument. They are all image and attitude. Jazz, always touted as America’s one true art form, is struggling to survive. The major record labels shy away from niche markets, and promotion and marketing money goes with the youth demographic, which is generally under-educated about the art of music. This presents a cultural and ethical problem.”
by Sal Polcino

Below are a few charts on and graphs on the great and sadly highly misunderstood art form.
