Kame = Pile

Kettle and Kame Topography

Hard on the defunct gravel pit of the northwest side of the preserve is the deposit of glacial rocks washed to some extent by melting ice the former owners of the pit were turning over for profit with the averted result of destroying the water sources for the ecosystems of the future preserve.

The deposit is called a kame. Kames are the obverse of kettles, formed with an enormous remnant of glacial ice melts in place leaving a substantial depression. A kame is formed when earth gathers in a depression formed by meltwater running over a glacial surface. When the glacier melts (in this area the ice wash a mile high), the washed earth is left as a steeply sided pile we experience as a hill.

Water flowing beneath glaciers forms the long, ridged hills, eskers, we explored in yesterday’s post.

Long, Ridged Hill

A Look at an Esker

Well formed, sinuous, graded on both sides, eskers can be mistaken for man-made earthen structures, such as railroad embankments. Here is an example, nine-tenths (0.9) of a mile long substantial enough to direct the flow of Fall Creek. On entering the Malloryville esker bed the stream makes a right angle turn.

Here we are at the foot of the primary esker of Malloryville Preserve (it is marked as such on the information placard of this series first post). The slope to the right is the esker. A swamp lies to the right.

This video provides a better feeling for this esker.

Turtle Socks

Flowers from Mars

Two kettles of the preserve represent a pond and, below, a bog. Here is a photograph from the observation platform using the IPhone 7. I brought along the Canon dslr and 100 mm “macro” lens for the stars of this show…..

….purple pitcher plants (scientific name: Sarracenia purpurea). In past years, the central observation deck cut-out, hosted healthy pitchers. Today, invading high bush blueberries from the bog margin, crowded out the pitchers and the only flowering plant were among the grasses 8 to 10 feet away. My goal was photographing the extraordinary flowers.

Each flower rises from the base on a strong stalk. Here are the pitchers, also called “turtle socks”, flooded with sunlight.

A flower unlike any I have experienced, like the carapace of an insect, the reproductive element underneath a hood.

The posterior, there are only bracts.

I have, somewhere, macro images of the pitcher, with the downward facing hairs. Brought the wrong lens to capture this at a distance.

Flowing water

Water flowing from glacial till

Amazingly swamp, fen, bog, marsh can all be experienced during a thirty minute walk within this preserve. Here we are traversing a swamp …

…buoyed along on planking from recycled plastic.

The founders of this place, from a dairy farming family, strove for years to protect the water sources from encroachment by development, primary a duplicate of a gravel pit found on the other side of the Fall Creek valley.

This former acidic rainwater, percolating through glacial till, is buffered and chemically altered to create these multiform environments.

Water, flowing quietly, almost soundlessly, with powerful effect.

Formed by Water

Overview

Let’s digress from our exploration of Iquique, Chile for this attraction local to the Finger Lakes Region of New York State, an environment diametrically opposed to the Atacama desert. The Preserve at Malloryville opened 1997, eleven years after we moved to our home our home on Fall Creek (see header photograph).

The correct name is the O.D. von Engeln Preserve at Malloryville. I knew this name from his Finger Lakes geology book obtained from the library and read closely in the early 1990’s. It helped me understand the landscape among which our home was set, in 5 minutes walking distance from the future location of the preserve.

The text from the above information placard at the preserve entrance says it all:“Wetland habitats are shaped by the water that supplies them: the amount, how it moves, and the minerals it carries. Malloryville’s eskers, kames and kettles control the rate of delivery of water to the surface and suffuse it with varied concentrations of minerals. As ground water bubbles to the surface at the base of these hills, distinctive wetland habitats form, each with its own unique community of plants. The preserve’s intense concentration of bog, fen, marsh and swamp habitats is the direct result of ground water moving through this unusually complex array of glacial features.

Before the preserve was opened I was familiar with the landforms described in the above placard. My son and I did his first camping on top of an esker outside our front door. We enjoyed hiking along Fall Creek.

Frozen Fall Creek III

Across the years into a future

Gratitude for miracles witnessed is my emotion for this series, “Frozen Fall Creek.” Eleven 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.

Frozen Fall Creek II

Natural Ice Sculpture

My last post, “Frozen Fall Creek I”, ended with macros of Ice Crystals on a bed of frost over creek ice within sight of our former home, a restored water mill. I continued on the ice, following the creek to this spot were the stream bed turns 90 degrees, changing from a southerly to a western flow.

Here I encountered an open course where constant water motion resisted freezing. A few frigid days later, the course had an amazing transformation.

Last To Freeze, Fall Creek

The transparent ice of the now frozen space retained the impression of movement, the surface rippled by current. In the following photograph, motionless ice crystals reveal the truth.

Ice Crystals on Water Frozen while Supercooled

In the intervening days, the constant motion resisted freezing while the water temperature dropped well past freezing to achieve a supercooled state. As the water temperature continued to drop, a fast transition from fluid to solid happened so quickly the movement of the water surface was preserved.
