"TO FIND" Confusion

Recommended Posts

All,

 

Maybe the 82 & 82 teams were as confused as I am by this station description:

 

portion of the DATASHEET:

QX0222 STATION DESCRIPTION

QX0222

QX0222''DESCRIBED BY NATIONAL GEODETIC SURVEY 1958

QX0222''0.55 MI NW FROM BOZEMAN.

QX0222''ABOUT 0.55 MILE NORTHWEST ALONG THE NORTHERN PACIFIC RAILWAY FROM THE

QX0222''STATION AT BOZEMAN, IN SECTION 6, T 2 S, R 6 E, 5 POLES NORTHWEST OF A

QX0222''ROAD CROSSING, 64 FEET SOUTHWEST OF MILEPOST 141, 94 FEET SOUTHEAST OF

QX0222''THE SOUTHEAST RAIL, 29 FEET SOUTHWEST OF A TELEPHONE POLE, 3 FEET

QX0222''NORTHEAST OF A FENCE, 2 FEET NORTHWEST OF A WHITE WOODEN WITNESS POST,

QX0222''ABOUT 3 FEET BELOW THE LEVEL OF THE TRACK, AND IN THE TOP OF A

QX0222''CONCRETE POST PROJECTING 5 INCHES.

 

Track runs 322 TN away from the Bozeman, MT RR station. This means to me that you can

 

have a measurement either SW or NE of the rails.

 

MP 141 is on the right (NE) side of the NE rail at the given distance from the RR

 

station. An existing fence in poor repair is about 75 feet NE of the NE rail. There is a

 

line of telephone poles about 94 feet SW of the SW rail but no evidence of a previous

 

fence line.

 

Some ground disturbance from firebreak bulldozing both sides and maybe a new siding since

 

1957 on the left (SW) side of the main line - but well within that 94 feet distance.

 

Looking for ideas on which side of the tracks I should look on when the snow goes off.

 

Thanks, ML

When a series of marks were placed along a rail line, it was not uncommon for the descriptions to assume the railroad had a fixed direction between cities, despite any bends along the way. They did not use a compass in this situation. If the line went mostly south, then "Railroad South" was the forward direction of the track no matter what the map said.

 

Try this interpretation and see if the description makes any more sense.

My thought while there was that the distance from the milepost is along the rail - one way or the other - and then turn a right angle to go the other distance. Was/is there a standard method to do this?

 

I covered all that ground, but with tall grass under 4 inches of snow and likely some loess since 1957, really didn't have much hope.

 

Thanks, ML

All,

Don't think that I will have to worry about RR Bulls if I go after this one; but the RCMP might object.

On Montana's extreme list as 'Northern Most". Who can a guy trust any more! ML

Note: In the full DATASHEET the two North Dakota marks use the correct bearing for their "REFERENCE OBJECT". I will send NGS a correction. Does "holoscenes.com" take corrections?

 

If it stays cold & snowy, I'll work on the true Montana north mark this afternoon.ML

Yes he does take corrections, he's a regular on this forum (Jim). Just go to holograph and send him an email.

 

But as for the Montana "northernmost" mark, since that is in Canada, holograph may want to exclude it. A good number of IBC marks that made it into the NGS list are actually in Canada and are attached to the closest US state and county.

 

Basically they were stations (mostly tri-stations, but some bench marks) used to survey the actual border monuments and are usually within a few miles of the border. I see them frequently in Maine and New Hampshire (or I should say across the border from Maine and New Hampshire) and I have logged a number of those. As for counting them for Holograph's extreme stations, that's his call.

All,

 

Continuing to play with Montana's extremes (not counting the -6F we have right now with a Christmas Bird Count to do tomorrow) I have found that many of the many Boundary Monuments along the 49th Parallel are listed in the wrong county. I don't suppose that this will have a very high priority, but I will let NGS know. ML

Perhaps one of the NGS folks will comment if there is a particular naming convention regarding the border. For instance, when interacting with the State Boundary Commissions of NC, VA, and SC, I asked why a mark exactly on the state line always was listed as a North Carolina marker in the data sheets. The answer is that for situations like this, the protocol is to list the marker in the state which comes first in the alphabet.

 

That means NC also gets the markers on the Tennessee line. But we lost a few to Georgia. :-)

Paul, I saw that too and I think it is for QX0468 that is on a pier of I-90. There is a sloppy hand drawn arrow pointing southeast from the BM 4753. I think I can see the X under the eastbound lane of I-90.

 

If you look to the southeast there is another notation for a benchmark--BM 4769 with an obvious bent arrow drawn to the west (although it doesn't seem to point to a current NGS mark, it looks like the X is along a building and nearby QX0225 is on a building--the station).

Paul & mloser,

 

thanks for your time on my little project. I think that BM 4679 is QX0225. Its elevation in the DS is given as 4772.47. I think the difference there correlates to a recent geoid correction of elevations in this area - if direction of correction is correct.

Thanks, ML

My blunder. The "spooky place" in Paul's post #13 still stands.

 

Now for a new "confusion" one that I stumbled across while randomly map pinning TOPO with possible winter accessible points.

 

Is there anyone working Yellowstone Co, Montana who could run out to Broadview and get the LAT/LONG for AI3752 R 537 RESET 1999 . The current DATASHEET places it in Madison County at the same coords as AI3758 R 574 RESET 1998. It should be at RV0681 R 537 1980 which it apparently replaced.

 

Exerpts from current DATASHEET retrieved today.

There are several marks in that immediate area. Maybe I'll try for them on my next visit to my son in Roundup.ML

Subtitle: reading the fine print.

 

In reference to QX0399 (B 4 in the 1907 Precise Level Net from Butte to Huntley, Montana).

 

In preparation to fill out a recovery form I noticed that the mark was not found, but described in 1958 as being stamped with the elevation and "B 4"; followed by "GOOD" recoveries in 1984 and 1987 with out any mention that the cap has only the elevation stamped and neither the designation or the date. See my photo of the old style disk in the log.

Did I really find the original mark? Note: Numerous of these 1907 disks were stamped at a later date.
