JEANCON] EXCAVATIONS IN THE CHAMA VALLEY t 
DIMENSIONS 
The following are the dimensions of the ruin. 
PLAZA NO. 1 
Running north from the southeast corner to the beginning of the 
indentation is a row of rooms 104.77 m. in length. Projecting from 
this point, running north, is a row of rooms 32.30 m. in length. 
From the beginning of the indentation in the east line, running west 
to the center of the indentation, is a row of rooms 51.30 m. in 
length. 
From the center of the indentation, running to the northeast corner 
of the same, is a row of rooms 60.96 m. in length. From the north- 
east corner of the indentation, running west to the gateway, is a row 
of rooms 43.33 m.in length. Here the row of rooms ends, but 39.48 
m. north of this point is the beginning of another row. Beginning 
at this point and running west is a row 11.4 m. in length to an 
opening. Whether this was another gateway, or whether the rooms 
have all been washed out, it is impossible to tell now, as there is 
no trace of the foundation stones. The opening is 8.83 m. wide, 
then the walls begin again and continue west for 6.42 m. 
From the north-central corner or west line of plaza No. 1 running 
south is a row of rooms 207.65 m. long. 
From the southwest corner running east to the southeast corner is 
a row of rooms 115.44 m. long. 
PLAZA NO. 2 
From the northeast corner, including the round room (the round 
room is 5 m. inside diameter), to the northwest corner the row is all 
washed out; the distance is 77.74 m. 
From the northwest to the southwest corner, running south, is a 
row 91.99 m. in length. This does not include the row projecting 
from the southwest corner of plaza No. 2. 
From the southwest corner to the southeast corner, running east, 
is arow 78.94 m.in length. From the southeast corner to the north- 
east corner, running north, is a row 91.23 m. in length. Projecting 
south from the southwest corner of plaza No. 2 is a row of rooms 
35.28 m. in length. The general orientation of the rooms varies 
from 3° to 17° from the magnetic north. The greatest variation 
occurs in the southwest row of plaza No. 1. At the southwest cor- 
ner of this plaza. the variation is only 3°. As the rooms extend 
north they form an arc and at a point 32.02 m. from the corner 
the variation is 17°. This is the greatest variation in the whole 
2209°—Bull, 81—23. 2
