Know all by these presents, that the undersigned hereby constitutes and appoints
Richard L. Voliva III, Vaishali S. Bhatia and Stacey Foland, signing singly, the
undersigned's true and lawful attorney-in-fact to:

(1)	prepare, execute and file, for and on behalf of the undersigned: (a) Form ID
(Application for Edgar Access) (including any renewal thereof); (b) Forms 3, 4
and 5 (including amendments thereto) in accordance with Section 16(a) of the

(2)	do and perform any and all acts for and on behalf of the undersigned that
may be necessary or desirable to prepare and execute any such Form ID
(Application for Edgar Access) (including any renewal thereof), Form 3, 4 or 5
(including amendments thereto) or Schedule 13D or 13G (including amendments
thereto) and timely file that Form or Schedule with the United States Securities
and Exchange Commission and any stock exchange or similar authority, and provide
a copy as required by law or advisable to such persons as the attorney-in-fact
deems appropriate; and

(3)	take any other action of any type whatsoever in connection with the
foregoing that, in the opinion of the attorney-in-fact, may be of benefit to, in
the best interest of, or legally required of the undersigned, it being
understood that the documents executed by the attorney-in-fact on behalf of the
undersigned pursuant to this Power of Attorney shall be in such form and shall
contain such terms and conditions as the attorney-in-fact may approve in the
attorney-in-fact's discretion.

	The undersigned hereby grants to each such attorney-in-fact full power and
authority to do and perform any and every act and thing whatsoever requisite,
necessary, or proper to be done in the exercise of any of the rights and powers
herein granted, as fully to all intents and purposes as the undersigned might or
could do if personally present, with full power of substitution or revocation,
hereby ratifying and confirming all that the attorney-in-fact, or the
attorney-in-fact's substitute or substitutes, shall lawfully do or cause to be
done by virtue of this Power of Attorney and the rights and powers herein
granted.  The undersigned acknowledges that the foregoing attorneys-in-fact, and
their substitutes, in serving in such capacity at the request of the
undersigned, are not assuming, nor is HollyFrontier Corporation or its
affiliates assuming, (i) any of the undersigned's responsibilities to comply
with Section 16 or Sections 13(d) or 13(g) of the Securities Exchange Act of
1934 or (ii) any liability of the undersigned for failure to comply with such
requirements.  This Power of Attorney does not relieve the undersigned from the
undersigned's obligations to comply with the requirements of the Securities
Exchange Act of 1934, including without limitation the reporting requirements
under Section 16 or Sections 13(d) or 13(g) thereunder.

	The undersigned agrees that each such attorney-in-fact may rely entirely on
information furnished orally or in writing by or at the direction of the
undersigned to the attorney-in-fact.  The undersigned also agrees to indemnify
and hold harmless HollyFrontier Corporation and its affiliates and each such
attorney-in-fact against any losses, claims, damages or liabilities (or actions
in these respects) that arise out of or are based upon any untrue statements or
omissions of necessary facts in the information provided by or at the direction
of the undersigned, or upon the lack of timeliness in the delivery of
information by or at the direction of the undersigned, to that attorney-in-fact
for purposes of executing, acknowledging, delivering or filing any Form ID
(Application for Edgar Access) (including any renewal thereof), Form 3, 4 or 5
(including amendments thereto) or Schedule 13D or 13G (including amendments
thereto) and agrees to reimburse HollyFrontier Corporation and its affiliates
and the attorney-in-fact on demand for any legal or other expenses reasonably
incurred in connection with investigating or defending against any such loss,
claim, damage, liability or action.

This Power of Attorney shall remain in full force and effect until the
undersigned is no longer required to file Form ID (Application for Edgar Access)
(including any renewal thereof), Forms 3, 4 and 5 (including amendments thereto)
and Schedules 13D and 13G (including amendments thereto) with respect to the
undersigned's holdings of and transactions in securities issued by HollyFrontier
Corporation or its affiliates, unless earlier revoked by the undersigned in a
signed writing delivered to the foregoing attorneys-in-fact.  This Power of
Attorney does not revoke any other power of attorney that the undersigned has
previously granted.

	IN WITNESS WHEREOF, the undersigned has caused this Power of Attorney to be
executed as of the date written below.
