With the assistance of the Yukon Geological Survey, Dr. Paul Sanborn was able to visit the terminus of the Klutlan Glacier, a major outlet glacier which originates in the Alaska portion of the St. Elias Mountains. The stagnant terminus has a thick cover of debris, including a large component of White River tephra, providing enough soil material to support a boreal forest. Field work occurred on July 8, 2007, and results were published as:

This image is part of the outbound sequence of aerial images obtained on the helicopter flight to the Klutlan Glacier study site. The sequence starts from the base camp at the White River crossing on the Alaska Highway and heads south, to a point just upvalley of the debris-covered terminus (approx. 10-15 km from Alaska border), and turning back north to the landing spot on the Generc River floodplain close to the study site (see Fig. 1 in paper).

The following Excel files are the primary lab reports from the Ministry of Forests analytical laboratory. At the time of this study, the lab reports would only use a minimal sample identification consisting of a sequential number (1, 2 … etc.) for each sample in a job. The submitter had to maintain their own records to link that sequential number in the report to something more meaningful – in this case, the tag number on the litterbag, the litter type, and the plot number – as recorded in my consolidated file Kenneth Creek Litterbag Sample Numbering.xlsx
Two files contain the complete records of initial litter materials and recovered litterbag contents, with some limited summaries of mean values by treatment and recovery date:
Item is the manuscript by Sanborn and Brockley entitled "Litterfall in a lodgepole pine fertilization experiment, Sub-Boreal Spruce zone, central interior British Columbia", which was submitted to the Canadian Journal of Forest Research but not accepted.
Includes the following data sets from Kenneth Creek installation litterfall collection:
Traps were emptied 3 times per year (May, August, October) and the weights of the sorted contents of each trap were reported for each collection interval in these files:
Sorted litter trap materials – composited for each plot and sampling date – were submitted annually to the Ministry of Forests and Range Analytical Chemistry Laboratory for analysis. The following files provide the link between the sequential sample numbers used in the lab result reports and the records of sampling date, plot number, and material type:
The following files have the original lab reports in the “Raw Data” pane, and the lab data merged with the sample identification information in the “Labelled” pane:
Four files have annual summaries of litterfall amounts, element concentrations, and element fluxes by plot and treatment:
More compact tabular summaries of the litterfall and element fluxes over the 4-year period of monitoring are in:
Three additional files provide pine foliar chemical data and preliminary estimates of the extent of element retranslocation from foliage prior to litterfall:
