The next thing to figure out in (3)
is what was meant by "... in the neighborhood of what is known as Cadotte Pass.
"In the neighborhood
" is a relative phrase that requires context for it to have meaning. If a person talks with a friend who lives two hours
away and says "I'm in the neighborhood,
" he probably means several minutes to an hour away.
Put another way "in the neighborhood of
" means a unit of distance or time smaller than the order of magnitude being used to bound it.
So for example if a person says an event happened in the neighborhood of the 1860's, the person is relating that the scale is years because the order
of magnitude bounding it is measured in decades. By saying this the person also loosely restricts the time period to the range between 1851 and 1879,
and implies an implicit bias for the years that fall after 1860 and between 1860 to 1869.
This also holds true for spatial relationships.
If a person who lives in Russia calls a friend in the US and says, "I'm in the neighborhood," he conveys that he's in the States because the
spacial order of magnitude bounding the distance is countries. This example is particularly relevant because it demonstrates how the expression can be
ambiguous. The friend in the US after hearing this is left to wonder, does my friend mean he's "in the neighborhood of my town or state" or does he
mean in the "US but far enough away that we won't be able to see each other in person?"
Bearing this in mind re-read the first sentence.
"Mr. Lumley states that about the middle of last September, he was engaged in trapping in
the mountains about seventy-five to one hundred miles (1) above (2) the Great Falls of the Upper Missouri (3) and in the
neighborhood of (4) what is known as Cadotte Pass (5)."
Since this is an article from the 19th century (meaning travel by boat, foot, and horse) and the author gives several broad scales of distance (IE/
the geographic territory is described as Upper Missouri, the location is painted incorrectly as above
the Great Falls and the distance to the
pass is a rough 75-100 miles to Cadotte Pass), it's probably fair to say that "in the neighborhood
" means within a days trip of Cadotte
Pass. Since Lumley is cited as trapping in the mountains it's also implied that he's moving on foot. According to
"the average pace of overland travel by an Indian band [is about] 25 miles per day.
that the author had earlier said Lumley was "75 to 100 miles away from Great Falls.
" This in and of itself suggests an error margin of
approximately 25 miles. Expressed in time this would equal a days journey.
So putting all this together, it can be said that:
- Cadotte Pass is ~60 miles, in a straight line, from Great Falls. Navigating by foot around impassable terrain adds 15 miles to the journey,
putting the total distance traveled smack at 75 miles.
- With a range of 75-100 miles suggests that Lumley was up to 25 miles, or a days trip out, from Cadotte Pass
- Based on the following two observations this gives an approximate search radius of 25 miles centered on Cadotte Pass or 1809 square miles!
Thankfully half this area is in the flats and since Lumley said the object crashed in the mountains we can restrict the search to the Rockies (~981
square miles). To view the search perimeter open up the kmz and double-click 25 mile radius around Cadotte's Pass and Probable search
perimeter of the 1865 crash.
The rest of the article is largely self-explanatory, but there are some details worth niggling over.
