Miguel Costansó
This day's march was only one league, as far as the Real Angosto de los Piñones. The streams from the mountain range were already running as a result of the snow that had fallen during the early part of the month, so that we found water in abundance at this place.

Fray Juan Crespi
Today we traveled only one league, and stopped at the camp of Los Pinones, where we had stopped on the 20th of September. We found all the arroyos now running, no doubt from the melting snow in the mountains, for at the beginning of this month it snowed a great deal all through the entire range.

December 17 To the Nacimiento River (Sept. 21-23).
December 19 To the Wagner Creek (Sept. 17-19).
