Thankfully the temps were mid 30s for the week we were there and are back to that again at the moment. We didn't have enough time with the dry blower. We took some rocks home to crush and got one speck out and a bunch of iron filings from the crushing equipment. Ran it through the centrifuge...
This is my son on our last day in the dirt earlier this month. We ended up mostly detecting that week, so only had an hour using the dry blower and brought the dirt home.
