Low on the Baldy/Iron ridge: 7220
Thus there's at least 2844 gain to Baldy
and at least 787 gain on return to Iron

Note: Delorme Topoquads shows GPS track has 13,545 feet of gain.  Can
this be correct?

That probably isn't accurate since for just Iron it also shows over 7000 ft of gain to the summit with 1000 ft of gain on the return.  That seems too high.

Thus I may need to add things up manually ...

low 7706
7903 - 7706 = 197 x 2

Iron 8007
Baldy 10064
Parking Lot 2000
Baldy Village is 4200+

Gain from Iron to Baldy (2 bumps on ridge):
Direct=10064-8007=2057
1st bump: 7227 to 7704 = 477
then 7320 to 7850 = 530
next low 7711
10036-7711=2325
low pt between baldy and west baldy: 9830
west baldy to baldy: 10036-9830=206
Thus total gain to Baldy is 477 + 530 + 2325 + 206 = 3538 ft

Gain from Baldy to Iron:
9950-9830=120
7850-7711=139
7704-7320=384
7941-7227=714
Total Gain: 120 + 139 + 384 + 714 = 1357

Total Gain for the day: 7200 + 3538 + 1357 = 12095
