Visited site from about 1545-1630.
Chose tower site at top of (very minor) hill. Although soil at the tower was quite dry, chose more representative lower ground for rad stand and soil. Rad has view of minor trees (we avoided being next to slightly larger ones). Soil solar panel might be in field of view of rads, but judged negligible.
Soil was clayey, but slightly drier on top than site 3. Also rocky. Still moist below. Didn't try to make "cap" over TP01 since layer crumbled. Sensors tested good (Gsoil just slightly positive).
