Well, perhaps the answer to that question is:
To access a Mine? And maybe that is
all they intended to do that day... check out a mine and go home. IMO.
Mines
In my 9/8/21, T#3, P#763 I reposted the mine research done by
@eptichka83 (T#2, P#292 & P#400), given JG had posted in his AllTrails logs information about mines he visited (recall, JG had labeled those hikes by mine, not trail names, IIRC). So here is a briefer summary for this discussion - may mean more to us now.
There are three mines on the route the family took.

1.
Liberty Lode (manganese): Off Hites Cove Road before the parked truck location
2.
Blossom #1 (gold): About halfway on "the loop", just off of the South Fork Trail
3.
Devils Gulch (gold): At the base of Savage-Lundy Trail
Below is a map image Eptichka83 created from
imgur.com. Previously I circled the Liberty Lode mine, where you can see a faint switchback trail up to it.
But now that I ponder this further, and with our new found knowledge of these trails, etc., I wonder if the family's goal was to check out the
Devil's Gulch Goldmine.
... Park where they did, go down the Savage-Lundy trail, check out the mine, and hike back before it got too unbearable. But what if they encountered someone or something at the Devil's Gulch mine that caused the beginning of the end for the family? While a tragic outcome, that kind of intent makes some sense to me, IMO.
