[pct-l] Temperature Ranges Temp Buttons

[Bill Batchelor]

Average Hiker 184 days.  By each hiker I put their days below.  To make that
easy, I just took the total numer of records for the hiker and divided by
24.  Most days had all 24 records.  So, this is a fair and quick way to get
a pretty good count.

Do you know how many nights total each hiker accrued?

I did some analysis of the temperature experiences of the five hikers that
carried those little temp log devices in 2006.  I found it very interesting.

These devices took a reading every hour.  These hikers were not together, so
the readings are from very different experiences and places.  This variation
makes the data all the more useful.

Some of the data is obviously anomalous (the anomalies seemed to be related 
to one hiker in particular).  The anomalies are easy to spot where the
temperature fluctuates too wildly in an hour like this 89, 92, 12, 93, 89,
86.   So, I removed the anomalies.

I was curious to see the number of nights around or below freezing.  Here is

what I found.

A couple hikers had nights around 20, though no more than two nights each.
These were very rare and were probably avoidable if they wanted to "hike
high, camp low".

Here are the numbers that I chose to look at: 

A = # of nights at or below 35
B = # of nights at or below 32
C = # of nights at or below 30
D = # of nights at or below 26

The numbers are collective and include all the nights in the lower temp
groups.  So, item A at "below 35" is a total including the nights below 32,
below 30, below 26.  Hence, item A includes all of A,B,C&D.  B includes all
of B,C&D.  C includes C&D.
