as yesterday, were surprisingly uncommon. Collected large bumblebees- mostly from Pedicularis capitata and Polygonum bistorta among willows along river bluff. Yellow wasptails were quite frequent. Mosquitoes too. Walked a mile or so along bluff, then turned inland. Still not much in the way of shorebirds. took a refreshing swim in a large tundra pond. Back by river bluff found a small sandy pond filled with some cart of invertebrates - mostly copulating. Collected a vial full. Returned to boat, picking up several more bumblebees, including 2 different species, on the way. Putto back to camp, snacked, then Niko and I tried for a short nap. Tom woke us up to report that village natives had seen caribou where we had been earlier, and were going up with rifles. We grabbed the camp boat and followed with camarades. Our first estimates of the herd were ca. 250; our last estimate was 3 to 4,000! they were bedded down, but 2 hunters were behind to speak them towards the hunters. We didn't want to interfere
