I've apparently caused some really interesting writing with my simple (maybe naive) question.

Meanwhile due to circumstances I kinda forgot about this thread, since we decided to postpone the trip to September and re-plan it to be suitable for people without winter gear and needed knowledge to use it, meaning we'll attack Oltar from Vrata.
Thanks to all who replied, both those who gave opinion in strange twisted way (and incidentally provided relevant info!), and those who took the question seriously (which it was) and warned about danger and ambiguity of previous replies. Result was really interesting, even philosophically tinted debate, in pure-blooded Slovenian style of course
From answers I conclude:
-conditions in Dnina still wintery and proper gear needed,
-approach to Oltar this way fu**** up and as naive unskilled hiker better worry about everything else than above point,
-end of August on any demanding pathless terrain conditions can always be wintery (with all respect dprapr but this seems slight exaggeration).
For final "twist" or explanation: plan was to hire guide for the trip who'd take me and one other person without winter knowledge and gear to Oltar. No one thought of that, ha?!
