Chiseled Marks and old Drill Holes - I love to see these, also.

Recommended Posts

Current two week road trip has produced a half dozen chiseled marks - one by feel only under a set of wooden steps.

I used GSAK filters to hi-grade for them, along with Mirc, USLS and older runs that contained a few B.M. disks.


Yesterday's southwest breeze on Lake Superior made for an easy kayak landing at USLS ROCK 1902




just east along the mainland shore line in the Apostle Islands National Lakeshore from the Little Sand Bay Ranger Station. 109 years of wind and water

erosion has exposed the copper bolt and made the lettering faint. Curious that the is no mention of the triangular arrangement

of drill holes around the mark; one of which contains a copper bolt and another residue of cementing material.


This was the last day of a three night kayak camping expedition to Sand, Ironwood and Bear Islands. Prettiest beach

was on the NE corner of Bear I N 47 01 34.7 W 090 45 02.1.




Others have posted neat pictures of this beach on Google Earth. kayakbird

A sample of Idaho and Oregon chisel marks - from east to west:


Most difficult to see CHISELED CROSS WT




Setting least likely to be removed PLN J 3 1903




Nice, sharp, chisel work PLN P 3 1903




Most remote PLN S4 1903




Neat rock structure PLN V 5 1904




A bit scruffy in 1920 G 21 1920




Mystery Mark - supposed be a chiseled square - long term typo or a RESET?


P 20 1920




It is on the correct RR culvert at the right L/L.




Any of these out east? MEL

Quite elusive, until someone cleared the blackberry vines. I've tried on this one 3 times, third was the charm!






There are a number of chiseled squares in the backroads between Watsonville, CA and Gilroy.

Yes. I hae posted this elsewhere, but it seems to fit Shirley's interest in chiselled marks.




Caching with my brother (Oh. It's only a 350' climb in a half mile, and there are four caches including this one from 2001.) "Okay. There's a benchmark. Let's go for it." Pisgah (1979) PF1048 was an easy find, with the two RMs. But near RM2, I found what's in the above photo. Copper bolt in a chiselled triangle (seems to be chiselled into the wod "Raymond") Nearby PF1048 is PF1049 (with no info, nor page.) I've asked Deb if this coudld be PF1049 (Pisgah 1934), but if her page has no info, how can she say? But, I'll guess that that's what it is.

Oh, well. It's a nice copper bolt in a chiselled triangle for Shirley.

I have found chiseled squares, crosses and triangles but Sunday I found a chiseled arrow. I know that these have been used as reference marks (eg., Sugar Loaf Mountain) but this one is listed as a vertical control: JU0646








My reading of Bulletin 21 of the Department of Conservation and Development State of NJ (this mark is described on page 106) suggests that the control was established as part of the 1919 leveling run. Seemed like an odd mark but then I realized that the surveyor used the shaft of the arrow as the indicator of the elevation (18.97')

Thanks for that documentation link.


If you do a Recovery to NGS, and submit that information, they may change the 'JU0646 HISTORY UNK MONUMENTED NJGS' date. Are there other PID's in that level run that could be updated also?


Don't have New Jersey in my GSAK files for a quick filter sort. kayakbird
