[pct-l] Stehekin detour Resupply question

[River Malcolm]

First my apologies if this has been addressed already. I have not been able to read the listserve regularly from the trail. 

I understand the current detour --Suiattle River Trail to Rainy Pass via Suiattle River Rd 26, star route 530, and Hway 20 -- involves no access to Stehekin (or Holden). 

Has anyone figured out somewhere to mail a resupply box that would previously have gone to Stehekin?  Also, does anyone have an estimate of the number of miles added by the detour ( for figuring how much food to send to Skyhomish and to the Stehekin-substitute, if there is one)?

Many thanks for ANY advice and guidance you can provide. 

Happy trails
River
