UVM COSMOGENIC SAMPLING

---

We sample most outcrops with a hammer and chisel. The Baffin Island outcrop pictured below had striated quartz viens demonstrating that little erosion had taken place.

---

We locate outcrops using airphotos, GPS and topographic maps.

---

We take great care to protect valuable samples!

---

We document each sample using the form below and using poloroid photos.
