Thanks to Google Earth. "Down the Hill" is in the centre |
Many visitors to Glen Innes have enjoyed a day’s fossicking at
“Down the Hill”, both on our
Wednesday Baptist Church trips and during Minerama. I’ve written about the
place in two previous blog entries (Quartz at Down the Hill and The BigSapphire). Several videos have also covered the area (one, two and three).

“Down the Hill” lies downstream of “Through the Fence” and upstream of “Underground River”.
Down the Hill is an area with many rocky outcrops and, most notably, an
abandoned channel through which the
creek only flows in flood. At one time this was the most productive area, but
the old diggings have mostly filled with sand and no-one seems too keen to
spend the day removing it when they could search among the rocks. At the lower
end of the channel the wash was at least two metres below the overlying sand.
The last we saw of it, there was lots of black jack and

presumably gems, but we
were beaten by inflowing water and finally by a flood which filled up the hole
with sand. Maybe one day, during a drought, fossickers will get another chance
to experience the thrill of working this spot.
At some time, probably in the 1960’s, a small mining operation
operated at Down the Hill. There was the remains of a shed or hut when I first visited the
place in 1988 but hardly any sign of actual mining. This was on the flat
immediately below where we parked. The only other sign of previous visitation was
a Tamworth 1 pint milk bottle I found in the creek just below old hut site.

One day's small finds - December 2009 |
The gemstones are the usual ones for Yarrow Creek –
sapphire, zircon, pyrope garnet, the occasional topaz and enstatite and, of
course, quartz. My one and only cuttable ruby came from here, as well as my
largest sapphire, best dog’s tooth crystal and biggest quartz

crystal. This is
more reflection of the sheer quantity of wash we found than its superior quality.
It’s a place I have never tired of visiting.
