Cessna 170 pilot reported a loss of control during landing in crosswind visual conditions; resulting in a runway excursion and ground loop. The pilot determined there was no damage to the aircraft; and coordinated a taxi back to the hangar.

Narrative

Was providing flight for a friend in my plane. He has not had any experience with tailwheel aircraft so I was providing him with a new experience. On final for runway XX tower announced wind 230 degrees at 10 knots. I thought about asking for change in the runway assignment to runway XY; but I could see the wind sock near the approach end and it didn't appear to show the same wind conditions as just announced. The sock showed a slower wind speed more closely aligned with runway XX. The three point landing was normal but very soon after touch down the plane started to turn to the right. Crosswind control settings did not correct the deviation and the right turn tightened to a ground loop. We stopped facing the opposite direction with the left wheel off the runway. Upon further inspection; the landing gear was still fully functional so we received permission from the tower to taxi back to the hangar with the safety vehicle following just in case we needed it. Lesson learned; I have always told myself that if a directional deviation began while landing to simply add power to reject the landing and go around. For some reason my mind was set that I had landed and I could recover from the tightening turn.Also; if a second runway is available and more closely aligned with the wind then take it. No award is handed out for handling a crosswind in a tailwheel aircraft.
