Emory—An Archacological Survey of Haleakala 247 
three platforms, which are situated respectively in the south, east, 
and north parts of the valley, are notable for the volcanic bombs 
used in construction. The isolated south platform is bordered by 
a wall less than 2 feet high, which forms a rectangle 15 by 7 
feet. The space within the walls is filled with sand and gravel 
forming a surface which corresponds with the slope of the ground. 
The poorly preserved east platform with dimensions about 
12 by 4 feet is similarly constructed. The north platform (PI. 
XXIII, 4) differs from the other two in the presence of a second- 
ary wall about 5 feet from the outer south wall, which divides 
the platform into two longitudinal sections. Due west of the north 
platform is an anomalous structure consisting of two walls forming 
a right angle that corresponds in position with the southwest 
corner of the platform. Near the entrance to Hanakuhi Valley 
are two solidly built ahus constructed of unmarked local stones. 
The north ahu measures 5 by 7 feet and the south ahu 5% by 9 
feet; both are 2% feet high and lie east and west. By standing 
on them the three platforms in the valley can be seen and the 
approach to the valley watched. 
We removed all the rocks of the south ahu and dug under 
it, discovering nothing. Excavation of north platform (Pl. XXIII, 
A) resulted only in a knowledge of its construction. A _ wall 
extending north and south for 19 feet along the Puu Kumu slope 
of the valley had been built up 2 feet. Then the side towards 
the slope had been filled in with two layers of stone, half as large 
as those in the walls, and then coated over with several layers of 
Sand. his made a terrace 5 feet wide, closed at either end 
by a solidly built wall. At the back of this terrace was laid a 
single course of volcanic bombs, averaging a foot and a half in 
diameter, and 3 feet back from this line was laid another row 
of bombs. The shallow space between was filled level with sand 
3 inches deep on the up valley side, and 12 inches deep on the 
down side. The terraced platform rests on hard-packed cinders in 
which bombs and pieces of lava are embedded. The south plat- 
form rests on a flat solid lava floor and is similarly constructed.
