2004-07-08	mh	The following markers were removed: m3631, m3607, m3596, m3595, m3648, m3585, m3604, m3577, m3605, and m3608. [Input: O710MH2.j]
2009-07-25	cJC	Ideally we would like to reestablish the previous squares following the site-wide grid for excavations this year. bP is not in the field this year and so her former assistant Adeeb is doing to surveying. Unfortunately J2 is down so low and is lacking in previously established points making it difficult to reestablish the squares. Today we tried to place some squares but they were in the wrong place. Tomorrow we will try again by placing to lines, one on the north-south grid and one on the east-west grid and then placing a stake where they cross. From there we can reestablish some squares. This may be less accurate than using the surveying machine, but right now it is impossible to put the points using the survey machine. [Input: T725CJC.j]
2009-08-01	cJC	There are still problems with the markers, they have not been entered into the computer yet and may not be accurate. We are awaiting the arrival of a new surveyor to double-check the points. Until then we will relay any markers before removing them so we can check them against older points if needed.

2009-08-05	cJC	Adeeb came to remeasure our markers today for the correct elevations. We hope to be able to have the measurements next week. [Input: T805CJC.j]
2009-08-26	cJC	After plotting the J2 loci from MZ22 it became apparent that they do not exactly match the squares of the previous years. This is not totally unexpected as we had many problems at the beginning of the season trying to reestablish the squares due to the small number remaining markers in J2 as well as the depth of J2 compared to the remaining markers. The differences are not substantial but should be noted. [Input: T826CJC.j]
