Only if the contents of the iframe and the parent are on the same domain.  There are security restrictions enforced on iframes which in most cases prevent you from accessing the iframe from the parent and vice versa.

Here's a bit of a discussion on the subject with a similar question to yours.  Also a bit of a solution for you provided you're using the same domain for both: http://bytes.com/forum/thread150689.html

DId you try parent.scroll(0,0)?
index1.htm

<iframe src="2.htm" height="200" width="300"></iframe>

index2.htm (iframe)
 
<a href="javascript:void(0)" onclick="parent.scroll(0,0)">click</a>

It will be cross-domain, but assuming that I can get access to the parents source code - is there any workaround from that perspecive?

Unfortunately for you, no.  If you try to access one document from the other (via the iframe) javascript will throw errors and not do anything else.

Is there a way - from within the iFrame - to force the iFrame to scroll up to the top of the iFrame or jump up to something like an anchor

Yes, you can tell the iframe to scroll itself or the parent to scroll itself.

From within the iframe or the parent (whichever you wish to scroll):

document.body.scroll(0,0) (as nick_bal mentioned)
Personally, I use document.body.scrollTop = 0;
