Fall Run Park

The verdancy of summer is best experienced in a narrow western Pennsylvania ravine. These places are particularly inviting after thundershowers wash the air crystal clear, polish the leaves to a glistening shine, and fill streams with roiling water. After the rain, the rising petrichor fills the valleys and tempts us to explore corridors winding under bowed …

Great Allegheny Passage

On May 21, 1975, a small train rolled out of the Baltimore & Ohio Railroad Station in Pittsburgh. At the head was a yellow, red and blue Chessie System locomotive, #6600 with asleeping kitten on the side. It was followed by a gleaming stainless steel Amtrak Silver Dome, #9401, and a vintage blue, white, red …

The Origin of Spring

By using this ruler, my favorite part of the year, spring, is lengthened. That magic day …

The messengers and their moving maps presume to provide detailed information absolutely needed to save family and property from harm in the face of imminent and sure …

Farewell to a Summer Love

August afternoons resemble the blazing passion of new love: intense and torrid. August evenings are the antithesis: gentle and serene. They are a mature experience that is like a long, tender embrace. On August walks I avoid the blistering, high-sky sun of midday and seek shelter in shaded, cool, stream-cut ravines. The forest umbrella blocks the …

The Dead of Winter

I have often tried to find the beauty in a frigid day. I have frequently searched for loveliness in a meadow swept bare and brown by icy winds. I have repeatedly tried to uncover elegance in snow-wrapped woodlands. My pursuits have always failed. I will always no more than tolerate winter. Each time I make …
