Exciting Change in Itinerary

I am leaving Salta. I have changed my itinerary to include an excursion further northward into the Andes Mountains. I feel the need to get to a village in the mountains. I hope to do some walking through some beautiful territory. My plans have to be tentative, since this is a remote area. Sometimes there is only one bus per day where I will be. And this is the rainy season. If it rains, a road may close for a day. So the plans are both tentative and flexible:

Jan. 18 Salta to Jujuy--2 hours, then Jujuy to Humahuaca, 3 hours
Jan. 19 Humahuaca to Iruya--3 hours leaving only at 10:30
Jan. 20 Iruya
Jan. 21 Iruya to Humahuaca--3 hours leaving only at 15:15
Jan. 22 Humahuaca to Purmamarca (Schedules unknown at present time)
Jan. 23 Purmamarca to Jujuy (Schedule uncertain), then Jujuy to Salta--2 hours
Jan. 24 Salta to Cachi--4 hours (only one bus
Jan. 25 Cachi to Cafayate (One bus only on Wednesdays and Sundays leaving at 9:05), then Cafayate to Tafi del Valle if not too late in the day

If you look back at my previous schedule, this puts me back on track. I will go from Tafi del Valle to Tucuman and continue as planned then. Now here are some images:
