Found as described. From the parking area closest to the Beltway, proceed on foot through the gate approximately 0.19 miles. It is shortly after a secondary trail at an acute angle on the left and shortly before the main train (an unimproved road, really) veers off to the left, and about halfway between those two points. Turn right (approximately east) off the trail and go cross-country about 125-150 feet to the mark and associated reference marks (HV2288, HV2289).
There was recent flagging around the marks when I visited, so obviously this station (or its RMs) is in current use. The slight displacement of the station, apparently a result of the growth of the tree by which it was set, has no doubt reduced the value of this station, unless its position has been measured in its present condition.
I believe the mark is made of metal, not white plastic as stated by a previous logger. I suspect no plastic would be considered sufficient durable when this disk was placed in 1930. However, this disk (and RM1) are white in appearance, and likely this is an enamel coating of some kind.
Also, the white construction material referred to in the same log is, I believe, a target for aerial mapping purposes. It's hard to see in the patchy snow cover.

View looking generally north showing relative position of this station and associated reference marks. Red arrow indicates station mark. Blue arrow indicates approximate location of RM1 (HV2288). Yellow arrow indicates location of RM1 (HV2289). Flagging is visible at all three disks.
Found this station as described. For some reason I didn't notice this PID in the database at the time, so I'm loading it now a few months later.
A large tulip-poplar tree is slowly pushing the benchmark out of position.

The disk is made from some white plastic instead of brass.

Station Burling is being slowly pushed out of position by this large tulip-poplar tree. The station was installed one foot from the tree when it was much younger. (Oooops - not a good idea.) At some point in the past, someone put some white construction material around Burling and Burling reference mark 1, and 2 ends of it frame the station.
