According to an interesting map (Hawai'i Island Atlas and Maps, by Environmental Designs Hawai'i), the 1984 flow stopped about 4 miles uphill from the Hilo Country Club which appears to be near the Saddle Road at around mile marker 8. That translates roughly to about 3 mi. south of the 12 mile marker of Saddle Road. The map doesn't have contour lines so the flow may not have been on course for the country club, but maybe would have moved toward Hilo to the south of the golf course.
The History Channel program just finished at 4:00p and will re-air at 7:00-8:00p. This is for Dish Network, don't know if cable or DirecTV has a different schedule. The series is called "Mega Disasters", the episode is "Hawaii Apocalypse". It discusses past eruptions and future possibilities with footage from Kalapana, among other things.
Hualalai is on a 200-year eruption cycle and is overdue. Mauna Loa is on a 20-year cycle and is also overdue.
You can hike to part of the 1984 flow on the Pu'u O'o Trail that starts on the Puna-side of the Saddle Road between mile markers 23 and 24, I think. The parking area has always been hard to see, but the Saddle Road realignment work has made it even more obscure. The trail goes out about 4 miles and may not be marked on the '84 flow and beyond. When the trail crosses old flows (1899, 1855, and 1880, in sequence), the trail is marked by ahu (cairns, stacked rocks) and a slight wearing of the patina on the flows. Sometimes, it takes careful observation to not get off track. If you do hike any trails, it's always highly recommended that you not add or subtract any ahu.
