Gratitude for miracles witnessed is my emotion for this series, “Frozen Fall Creek.” Thirteen winters after Pam and I walked Fall Creek as a solid walking path, the stream flows without ice most years. My son, whose family now lives in the house, and his wife recalling walking the creek a few years ago, not in the past few years.
Weather records support our recollections and observations: here is an analysis of Ithaca January temperatures. The years 2009 through 2019 show a warming trend in daily temperatures for both minimum and maximum.
Analysis
Excel I used to plot minimum and maximum temperatures (farenheit) for the 31 days of each January for eleven years 2009 – 2019. Click on the images of this post for a larger version.

Forecast
Pam and I moved to Ithaca 2011 and missed our Fall Creek winter walks, miss them even more now our weekend excursions are only memories. Here are January minimum/maximum average daily temperature projections from 2020 through 2044 based on the trend established from the 2009 through 2019 series. The trend is the solid color, projection the faded color.
Reading from the chart, if the current trend continues by January 2044 the average maximum daily temperature will be 47 degrees compared to 29 for 2009. In other words, the temperature never rose above freezing in the year 2009. By 2044 temperatures will be above freezing every day, on average, with daily minimums averaging 21 degrees.
From what I read, we can expect these warming trends to accerate within our lifetimes. My son named small mid-creek hummocks “islands” with numbers. Here is a view of his Second Island in late summer. What will Second Island be in 2044 late summer?
Memories
Reader of posts I and II of this series have commented about snow shadows. Here are the shadows produced from snow fallen on the vegetation of the last photograph: soft mounds to contrast with tree trunk shadows.

I prefer the composition of the following photograph. What do you think?
A combination of contrasting shadow forms.
