Late Fall in Echo Valley
Oak leaves float along a spring-fed waterway in Iowa's Echo Valley State Park near Fayette. While air temperatures are certainly cold enough for ice and snow formation, the lack of falling precipitation continues to reinforce the year old drought. Last week Iowa's state climatologist actually predicted a worse drought in 2013 based on over a hundred years of state climate records. Hope not.

A Peek Under Iowa's Topsoil
Near the fringe landscape between rolling farmland and northeast Iowa's driftless area, where the most recent glaciers missed scouring the land, there lies a variety of topography. An example is just north of Fayette, Iowa where this limestone quarry operation carves out some small hills. Notice the relatively thin soil supporting the meadow vegetation. Most of the Hawkeye state is built on sedimentary layers like these from ancient shallow ocean deposits. This is the source of many shell, coral and marine bottom creature fossils found throughout the state. Today this solidified mud and ooze from shallow seas makes great gravel (once ground to size) used for rural roads and paved road shoulders. Take a drive on Iowa roads and you'll now think about where the source material is found.

Lighting Up Burlington' s Masonic Temple Alley Door
Cobblestone Alley in
is perhaps as not as famous
as its close neighbor Snake Ally located just a half block away. But a stroll
down the real cobblestone pavement reveals a few home entrances and this
interesting door. Burlington,
Look a little closer at the door knob and discover a Masonic emblem, positioned a third turn to the right. Turns out this alley is the backside of the local Masonic temple. The building’s front faces east with its northeast corner, the traditional cornerstone location receiving the first rays of light each day. That orientation means this weather beaten door receives the last light of the day. And in between, according to the Masons the walls hold enlightenment.

Oelwein Yard's Retired Locomotives
Oelwein, Iowa once was home to a massive railroad maintenance yard. The expansive facility was located just a couple of blocks from downtown. And as with many changing industries, the Oelwein Yard diminished as lines no longer needed the facilities. However in an effort to preserve the past, local train enthusiasts several years ago secured some remaining building structures, rail related equipment and created the Oelwein Railroad Museum, part of the Hub City Heritage Corporation.
Some of the rail collection exists outdoors. These locomotives are among the fleet of rail cars which also features an old wooden caboose from the 1910s and restored last year. The outdoor site is also an attraction for photographers.
While I was there a few weeks ago, a family of three arrived and were greeted by a woman with an array of photo gear. She led the young family around to the various trains, posed them and took their portraits. She told me that the family will use these photos as part of their holiday cards. She also said that the family loves trains - especially the preschooler and his Dad. My reaction was, well who wouldn't like these old beauties? Just as long as they don't block your way from point A to B.

Veterans Day 2012 - Spirit of the American Doughboy
Just off the Lincoln Highway in Mechanicsville, Iowa is a tribute to World War I American soldiers. Known as the "Spirit of the American Doughboy" the sculpture was designed by E.M. Viquesney and sold to cities throughout the 1920s and 30s. A detailed story of this design and history including its similarity to the Statue of Liberty can be read here.
Some 300 of these statues may still be found in cemeteries, parks or near government buildings throughout the country as a tribute to the American fighters of World War I. On this day with its genesis as Armistice Day, we remember all veterans and their contribution to American freedom and liberties.

Reaching for the Sun
Late autumn reveals interesting tree growing behavior. These rocky cliffs are north facing which does not allow for much direct light on developing trees. As a result stands are generally branch-less until they reach a certain height to create a canopy. Now that the leaves have fallen the nearly vertical trunks can be observed reaching for the sky without impediment.

Underwater Animal Tracks - Protofossil Factories
Animal tracks can be found around water sources. Such is the case with these
and deer tracks through backwaters of the Cedar River at Palisades-Kepler
State Park near .
Given the right weather, geologic conditions and time these now watery tracks
could become hardened fossil tracks. However, even in drought times that
eastern Mount Vernon, Iowa Iowa
has experienced in 2012 it is unlikely that these tracks will survive intact
following the next rainfall let alone the eons of time. But somehow fossil tracks
do show up in the geologic record. We shall see.
