General Location and Strategy: SN 15 is located outboard of the
youngest circumferential fissures on the northeast flank of the volcano.
Field Notes:
Days measured: 03 Jan 00 - 04 Jan 00(N of Volcan Chico)
Monument SN15 is a small (~(7, 2?)m wide) patch of pahoehoe amongst a'a, located approximately 20m west of a large N/S- trending crevasse. A cairn built on top of the pahoehoe block is (uplifted) ~3m.
Antenna height: 0.736m + 0.108m = 0.844 m
Antenna offset: 0.353m

2000 Results
Data are from a single GPS day (1/14/00). Solution was made by fixing SN11.The uncertainty reported here uses the sigma of the single difference observations as a scaling factor and is obviously a gross underestimate.

Site 15, looking north from saddle just beyond Azufre vent. Best route
is to traverse left from bottom of scree slope, then find as much pahoehoe
as possible. It is critical to hit a bridge over the deep fissure.
Site 15, looking east from nearest pahoehoe.
