Currently (Jan 2012) there are a significant amount of works in
the area. You can still complete this but be sensible about where
you park
Background
Across the paddocks towards the sea from GZ you will observe a
location where the Akatore fault has ruptured. The fault scarp that
resulted has cut across marine terraces that formed during the
pleistocene period (2,588,000 to 11,700 years ago). The Akatore
fault is one of the larger faults in the Dunedin area. Other named
faults include the Titri fault and the recently discovered Green
Island fault. Studies show that the Akatore fault has had activity
in the last 1-10,000 years. The Titri fault hasn't had activity for
90,000 years and the Green Island fault is thought to be the cause
of Dunedin's most recent sizeable earthquake in 1974. Further
research about the Akatore fault can be done
here. Further general reading (ODT articles) can be found
here.

Requirements
0. Preface any email with GC2G806 Fault Finding in the
subject line and title and clearly note the question number and
answer. Do not wait for a confirmation email to log but be prepared
to be asked for additional information if your answers are
slim.
1. At or near GZ the fault scarp should be clearly visible
looking towards the sea. Don't waste time using streetview to
observe as it isn't really visible. Prove that you've found the
scarp by either physically describing it (height, visible length,
direction of slope etc) or sketch or capture a picture of it with
you or your GPSr included. Email answer or photo/sketch to
gcstegan"at"gmail.com
2. Using the further research resource: when were the last two
thrust events and how much uplift occurred for each? Email
answers.

Stegan’s EarthCache Masters Programme
It is not very feasible for many New Zealanders
to get past the Bronze level on the earthcache.org programme becase
you need three states for Silver which means leaving the country!
So, as in 2010 I've decided to run a little sideshow on my new
earthcaches this year... with the following points
system:
5 points: First to find
3 points: 2nd to find
1 point: Logging a find
1-5 points: Special bonus questions.
At the end of 2012, I’ll issue certificates
for 1st, 2nd and 3rd.
